Activation energy is the amount of energy required in a chemical reaction.
Enzymes lowers the activation energy by increasing the rate of reaction.
The energy required for a reaction to start is called activation energy. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.

Now to knock out your other choices:
B. is wrong because:
A scientific theory does not predict. It can serve as a basis for a prediction, or what you call a hypothesis, but it does not predict an outcome.
C. is wrong because:
As mentioned earlier, a theory is WELL-SUPPORTED by evidence and previous research.
D. is wrong because:
