The error is most likely C. Hello quoted is proper. ("Hello") Eliminate A. Hello is proper as well so eliminate B. Now, we are at C. I Believe this is the answer since it is 100 quoted ("100"). 100 quoted does not make since unless used in a sentence such as "I bought 100 apples today for a good price!" D cannot be the answer since it is 100 all by itself. Thus, your answer should most likely be C, "100".
