Detailed Solution

A catalyst is a substance which alters the rate of reaction without taking part in the chemical reaction. A catalyst lowers the activation energy of the reaction to increase the rate of chemical reaction.

Catalyst works on intermediate complex theory and it does not change the Gibbs free energy of the reaction, equilibrium constant of the reaction etc. 

Hence, option (A) is correct.
