To answer this question, you need to understand the difference between "its" and "it's".
Option A) Its - This option is incorrect because "its" is the possessive form of "it". It is used to show that something belongs to or is associated with something else. However, in this sentence, we are not referring to something belonging to or associated with "rain", but rather we are talking about the weather condition itself. Therefore, "its" is not the correct choice.
Option B) It's - This option is incorrect because "it's" is a contraction of "it is" or "it has". In this sentence, we are not trying to say "it is going to rain soon", but rather we are using "it" as a pronoun to refer to the weather condition itself. Therefore, "it's" is not the correct choice either.
Option C) None - This option is incorrect because both options A and B are incorrect. We need to choose between option A and option B.
Option D) 1 or 2 any is correct - This option is correct because neither "its" nor "it's" is the correct choice in this sentence. The correct choice would be to use "it" without an apostrophe, as in "It is going to rain soon."
The correct answer is D) 1 or 2 any is correct.
