Answer:

The catalyst decreased hte activation energy of the reactants (answer A)

Explanation:

The activation energy is the energy required by the reactants to perform a specific reaction, as you can see in the Figure.

This has a direct impact in the speed of reaction, being that the lowest the activation energy is, the fastest the reaction.

The catalyst function is to decrease this activaiton energy and it's offen used when the reactions are to slow (several hours or days to happen).

In conclusion: Adding a catalyst decreases the activation energy of the reactants and increases the speed of reaction.
