To answer this question, we need to understand the data types of the variables x and y.

In the given code, x and y are declared as follows:

Dim x, y as integer

In this declaration, the variable x is not explicitly assigned a data type, while the variable y is explicitly declared as an integer.

Let's go through each option to understand why it is correct or incorrect:

Option A) x as integer and y as integer - This option is incorrect because the variable x is not explicitly declared as an integer.

Option B) x as variant and y as integer - This option is correct because when a variable is not explicitly assigned a data type, it is assigned the default data type, which is variant. Therefore, variable x is a variant, and variable y is explicitly declared as an integer.

Option C) x as integer and y as variant - This option is incorrect because the variable x is not explicitly declared as an integer.

Option D) x as double and y as integer - This option is incorrect because the variable x is not explicitly declared as a double.

The correct answer is B. This option is correct because x is a variant and y is explicitly declared as an integer.

To answer this question, you need to understand the concept of a Timer control.

The Timer control in programming is used to execute a piece of code at regular intervals. It allows you to perform a specific action repeatedly after a certain time interval.

The Timer control typically contains one event, which is the Tick event. The Tick event is triggered every time the specified interval elapses. You can write code in the Tick event handler to perform the desired action.

Based on this information, let's go through each option:

Option A) 1 - This option is correct. The Timer control contains one event, which is the Tick event.

Option B) 2 - This option is incorrect. The Timer control only contains the Tick event.

Option C) 3 - This option is incorrect. The Timer control only contains the Tick event.

Option D) 0 - This option is incorrect. The Timer control contains the Tick event.

Therefore, the correct answer is A) 1. The Timer control contains one event, which is the Tick event.

To answer this question, you need to understand the default properties of a data control.

Option A) Connection - This option is incorrect because the default property of a data control is not the connection. The connection property is used to establish a connection to a data source.

Option B) Line - This option is correct because the default property of a data control is the line property. The line property determines the type of line that is used to display data in the data control.

Option C) Shape - This option is correct because the default property of a data control is the shape property. The shape property determines the shape of the data control, such as rectangular or circular.

Option D) Records - This option is incorrect because the default property of a data control is not records. The records property is used to store and manipulate data records.

The correct answer is B,C. The default properties of a data control are the line property and the shape property.
