D.She wants to study music in all of it's various genres.

Answer:B looks correct but is a bit tricky ,am I correct.

The apostrophe is used when the two words are put together

it is ---> it's
When there is doubt, the possession use (for example: the farmer's cow)does not rate an apostrophe.
So I believe you are correct.

Here is an example from Wikipedia:

"That noise? It's just the dog eating its bone."

Apostrophes are used for contraction. You are correct!

Yes, you are correct that option B is the sentence that uses an apostrophe correctly. In this sentence, the apostrophe is used in the contraction "it's," which means "it is." The correct use of the apostrophe is to indicate that a letter has been omitted in the contraction.

Option A is incorrect because it uses "it's" instead of the possessive form "its" to show that the scenery belongs to the movie. Option C is also incorrect because it uses "it's" instead of "its" to indicate possession or ownership of merits. Option D is incorrect because it uses "it's" instead of "its" to show that the music belongs to the various genres.

To identify the correct use of an apostrophe, it is important to understand the difference between "it's" and "its." "It's" is a contraction of "it is" or "it has," while "its" is the possessive form of the pronoun "it." Remember that "its" does not have an apostrophe, but the contraction "it's" does.
