    If this is that MC question then the answer is D.

    Explanation:

    The correct answer is D. The energy needed for a chemical reaction is called the activation energy. This energy is to be present in order for the reaction to happen. This can be achieved by supplying or releasing heat from a system of reactants. This can achieved faster by using a catalyst.
