Well if I’m reading correctly it may stem from persona experience
Answer:
It is either A. She is disappointed with her assignment. OR B. She is suffering from physical discomfort.
When the subject needs to be emphasized more than the action performed,the active voice is used.So (a) is correct
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.
