...inactivates an enzyme. This is called enzyme inhibition. It can be at the active site or the allosteric site.

Inactivates.

Actually it could be either. The question is too general.
For example an allosteric effector usually activates an enzyme. However there are also many cases of negative allostery (inhibition).
I'd say probably A (like for example Ca2+ activates calmodulin) but I insist that the question is incorrectly formulated.
