The correct option is d: "Non-competitive inhibitors bind to a site other than the active site."

Explanation:

The active site of the enzyme is where the substrate binds. When this binding has taken place, the enzyme is able to convert the substrate into products. If a competitor binds to the active site due to its complementary structure, the substrate will be unable to bind and therefore, no products will be formed - this type of molecule is referred to as a competitive inhibitor. A non-competitive inhibitor is called as such because it is not competing to bind to the active site of the enzyme.

Hope that answers the question, have a great day!
