Given below are two statements:
Statement $I$: Low temperature preserves the enzyme in a temporarily inactive state,whereas high temperature destroys enzymatic activity because proteins are denatured by heat.
Statement $II$: When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme,it is known as a competitive inhibitor.
In the light of the above statements,choose the correct answer from the options given below:

• A
  Statement $I$ is false but Statement $II$ is true.
• B
  Both Statement $I$ and Statement $II$ are true.
• C
