    Option C is correct ...it is mainly due to increase in number of effective collisions Explanation:- When the temperature increases the number of effective collisions increases which is due to the increase in the number of activated molecules having energy greater than threshold energy.

    option A An increase in the rate of a reaction for a rise in temperature is due to  increase in collision frequency, shortening of mean free path and increase in the number of activated molecules. Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.
