Solution

The correct option is B Assertion is correct but Reason is wrong
Negative catalysts (Inhibitors): A catalyst which decreases or retards the rate of reaction is called negative catalysts.
A negative catalysts retards rate of chemical reaction.
Working of negative catalyst is not related energy of activation.
Hence, statement is correct but explanation is wrong.
Please note that enzyme inhibitors acts as negative catalysts. They bind to the allosetric site of the enzyme and decrease the rate of reaction.
