This looks like classic JAA. An ill-thought-out question is open to misinterpretation. Intelligent student thinks about it too much, and come up with the absolute right answer to the actual question, instead of the answer to the question the examiner was trying to write. I suspect the JAA answer is A, for is it not written "... thou art so sharp thee will cut theeself ...".
Good luck
