Why is the answer not (B) ?

Because the statement under this option is most good than others.

Thank you.

According to me, it is C. Because the enzymes work by providing an alternative pathway which requires less activation energy and not B. Because the three-dimensional structure that matters here is that of the active site but not the whole enzyme.

Yes, agree @Uthman.

The right answer is C.
