The sentence that uses a verb that agrees with It's pronoun subject is choice B, because it makes sense.
For choice A to make sense, it should be written as: "You are a very creative writer."
For choice C to make sense, it should be written as: "Lately you appear somewhat annoyed."
For choice D to make sense, it should be written as: "I was the one kid on time for her appointment."
