Answer:

The correct answer is option B.) "the activation energy".

Explanation:

In chemistry, a catalyst is defined as a substance that accelerates a chemical reaction without being consumed in the reaction. Catalysts affect the activation of energy of the reaction by lowering it. This happens because catalysts open new pathways of reaction that require less energy, therefore the alternative routes need lowered activation energy for the reaction to start.
