Solution

The correct option is E Assertion is false but Reason is true
A catalyst cannot alter the initial & final energy levels of reactants and products. It only provides a low energy pathway for the reaction to proceed. It lowers the activation energy but does not change the value of $Δ H$ .
Assertion is false but, Reason is true.
