1) The wrong sentence is D. In that case you don't need the possessive pronoum YOUR because what you need is a personal pronoun. YOU'RE is the correct form. However, as it is a question, the most suitable position for the pronoun is after the verb to be.
2) The incorrect sentence is C. In that case you need the pronoun THERE because the verb comes before its subject.
3) The incorrect sentence is D. In that sentence a personal pronoun +verb to be is needed. As it is talking about the weather the correct way is IT'S. The possessive adjective or possessive pronoun (its) is not correct for that context.
4) The wrong pronoun is in sentence B. When the sentence starts with the preposition TO you need the pronoun WHOM. The preposition can also be at the end of the sentence.

Tacit - Understood or Implied
A. Because it uses a dark setting and uses wording that give a dark vibe to he sentence.
I would choose "A" the best even though "C" also makes sense but not as much as "A" does. hope it works. :)
