D. More than one option is correct
Step-by-step solution
Competitive inhibition: The action of an enzyme may be reduced or inhibited in the presence of a substance that closely resembles the substrate in molecular structure. Such an inhibitor is called a Competitive Inhibitor of that enzyme. Due to its close structural similarity with the substrate, the inhibitor competes with the latter for the substrate-binding site of the enzyme. Consequently, the enzyme cannot participate in catalysing the change of the substrate. As a result the enzyme action declines, e.g, the inhi
