The Correct Option is C

Solution and Explanation

In tyrosinase, copper is associated as an activator. Tyrosinase is an oxidase that is the rate-limiting enzyme for controlling the production of melanin. Tyrosinase is a copper-containing enzyme present in plant and animal tissues that catalyzes the production of melanin and other pigments from tyrosine by oxidation. So, the correct answer is 'Tyrosinase'.
