I remember learning that the gradient is indeed a vector, so I agree with A)

Wait, is the gradient a matrix or a vector? This is starting to sound like a trick question. I'm going with A just to be safe.

C is interesting, but I'm not sure the gradient is infinite at a maximum point. I'll have to think about that one.
