Answer: The correct answer is Option C.
Explanation: Rate of reaction is defined as the change in the concentration of any one of the reactants of products per unit time.
All these factors affect the rate of the reaction.
Pressure and temperature can either increase or decrease the rate of the reaction.
Presence of catalyst increases the rate of the reaction.
Inhibitor works opposite to the catalyst. The presence of inhibitor decreases the rate of the reaction.
Hence, the correct answer is C.
