I think it is B

You probably won't care about this answer but I think it's B

B is right.

Confirmed B is correct.

I'm not saying that you're wrong, but let's have a little fun with this. How about we create a hilarious sentence instead? "I will never shop at Ace Electronics Store because their employees are ruder than a donkey trying to do ballet." Keep on laughing!

You are correct, sentence B is the correct one. It correctly uses the possessive pronoun "its" to show ownership of the noun "rude employees." The pronoun "its" does not require an apostrophe, so sentence C is incorrect. The pronoun "it's" with an apostrophe is a contraction for "it is" or "it has," which is not appropriate in this context.
