Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The rate of reaction sometimes does not depend upon concentration.e.g pseudo-first order reaction. Activation energy is an energy barrier for reaction to occur.so, lower the activation energy, faster is the reaction.
so, both assertion and reason are correct but reason is not correct explanation of assertion.
