Having two complete sentences next to each other is called a run-on. This is grammatically incorrect. We need to separate these complete sentences with either a period or a semicolon. C presents the same problem as A. D is grammatically incorrect and doesn't make sense.
Explain the difference between a colon and a semicolon.
A colon looks like a period on top of another period. The part before the colon has to be a complete sentence and the part after the colon explains the first part somehow, such as with lists, quotations, or explanations. A semicolon is a comma on top of a period. Use a semicolon with complete sentences on both sides of the semicolon and the two ideas are related to each other.
Black bears are omnivores, with _their_ diets depending on the season and where they are located. A. No change B. they're C. its D. it's
The answer is A. The subject is "bears", which is plural, so we need the plural possessive pronoun "their" since the diets belong to the bears. "They're" is a contraction and is the same thing as "they are". This doesn't make sense in the sentence. "Its" without an apostrophe is the possessive pronoun for singular subjects (ex: bear, car, child). "It's" with an apostrophe is also a contraction and is the same thing as "it is", which doesn't make sense for this sentence.
