“To throw down to” is an idiom which means “to set in the direction of “which is conveyed in the given sentence. Hence, (3) is the correct answer.

“In” is a preposition which is used for “bigger / larger areas or places”. So, ”in” is used with “Canada”. Hence, (3) is the correct answer.

“To shout at” is an idiom which means “to speak with high intensity “.In the sentence, ”at” is the best option. Hence, (2) is the correct answer.

The verb 'approach' is transitive and does not require a preposition when followed directly by its object. We say 'approach the dog' or 'approach someone,' not 'approach to/on/by the dog.' Therefore, none of the given prepositions (to, on, by) are correct.

When arriving at a specific location or destination like a station, airport, or building, we use the preposition 'at.' 'Arrive at the station' is the standard expression. 'Arrive to' is incorrect, and 'arrive on' is used only for surfaces like platforms or stages.

When requesting information from someone, we use the structure 'ask [person]' without a preposition. For example: 'ask Manu,' 'ask the teacher,' 'ask your parents.' We can say 'ask Manu about something' or 'ask Manu for something,' but never 'ask over/to/by Manu.' Therefore, none of the given prepositions are correct.

The adjective 'good' takes the preposition 'at' when describing skills, abilities, or proficiencies. We say 'good at languages,' 'good at mathematics,' 'good at drawing.' 'Good on' and 'good over' are not standard expressions in this context. This is a fixed idiom in English.

When congratulating someone on an achievement or event, we use the preposition 'on.' The correct phrase is 'congratulations on your success,' 'congratulations on your promotion,' or 'congratulations on winning.' 'Congratulations to' is used when addressing the person directly (e.g., 'congratulations to you'), and 'congratulations by' is never correct.

When describing a collision or impact with an object, we use 'crash into.' The bus collided with the tree, so 'crashed into a tree' is correct. 'Crash over' would mean going above something, and 'crash by' would mean crashing near something, not into it. The preposition 'into' shows movement from outside to inside contact with the object.

When requesting specific information or particulars about something, we use 'details of' to show possession or association. 'Details of your courses' means the information belonging to or about your courses. 'Details on' is sometimes used in less formal contexts, but 'details of' is more standard. 'Details above' would refer to something physically located above, which is not the intended meaning here.

The verb 'discuss' is transitive and can be used directly with an object without any preposition. We say 'discuss your plans,' 'discuss the issue,' or 'discuss the matter.' While 'discuss about' is commonly used in informal Indian English, it is not considered standard in formal English. Since 'on,' 'to,' and 'by' are all incorrect, the answer is 'None of these.'

The verb 'depend' takes the preposition 'on' when indicating what something relies on or is conditional upon. We say 'depend on the weather,' 'depend on circumstances,' 'depend on someone.' 'Depend over' and 'depend by' are not correct expressions. This is a fixed idiom in English grammar.

When dividing something into parts or portions, we use the preposition 'into' to show the result of the division. 'Divide the cake into three parts' means separating the whole into three sections. 'Divide to' is incorrect because 'to' shows direction, not division. 'Divide over' would mean distributing across a surface, which is not the intended meaning.

The verb 'enter' is transitive and is used directly with its object without any preposition. We say 'enter the room,' 'enter the building,' or 'enter the hall.' 'Entered into' is used only for agreements, contracts, or negotiations (e.g., 'entered into a contract'). 'Entered to' and 'entered in' are grammatically incorrect. Therefore, none of the given prepositions are correct.

When describing what someone is wearing or the color of their clothing, we use the preposition 'in.' We say 'dressed in black,' 'dressed in red,' 'dressed in a suit.' 'Dressed into' would suggest a transformation, which is not the case here. 'Dressed to' would indicate purpose, like 'dressed to impress,' which doesn't fit the context. The preposition 'in' is used to describe clothing, colors, or costumes.
