Increase in temperature increases the average kinetic energy of the reacting molecules.
Increase in pressure increases the number of effective collisions of the reacting molecules with themselves and the walls of the containing vessel.
Addition of catalyst lowers the activation energy of the chemical reaction.

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.

Increase in no of effective collision, the Rate of reaction increases.

Answer - C is correct. Because activation energy is constant for a particular reaction.

Temperature increases the number of collisions option A is true.

Both A and C are correct because as the temperature rises the kinetic energy of a particle rise which causes high collision between particle.

Actually, the rate of reaction is mainly influenced by the rate of collisions (no of Collisions) with an increase in temperature the rate of collisions increases hence rate of reaction increases.

As the temperature increases the KE is increased and the rate of reaction is also increased.
