Greater number of molecules having activation energy

(C) . According to the collision theory,the rate of reaction increases with temperature primarily because a larger fraction of molecules possess energy equal to or greater than the activation energy $(E_a)$.While the collision frequency also increases,the exponential increase in the number of molecules with energy $\ge E_a$ is the dominant factor.
