B.) Too much questioning is dangerous
Shakespeare's emotions in this sonnet and more specifically through this line is of sadness and depression, where he talks about how sad and lonely he feels and how he has this feeling of self-pity and sorrow,he also mentions using the word men's eyes that he feels whos people around are indifferent to his pain in spite of his evident sadness.
I personally think that the answer would be C
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.
