Solution
The correct option is D Both Assertion and Reason are incorrect
Competitive inhibition is a form of enzyme inhibition where binding of an inhibitor prevents binding of the target molecule of the enzyme, also known as the substrate. This is accomplished by blocking the binding site of the substrate - the active site - by some means. It is also called as selective inhibition. The competitive inhibitor resembles the substrate and binds to the active site of the enzyme. The substrate is thereby prevented from binding to the same active site. Hence the assertion as well as reason is incorrect.
So, the correct answer is option D.
