Assertion : Coenzyme nicotinamide adenine dinucleotide (NAD) and NADP contain a vitamin.
Reason : The association of co-enzyme with apoenzyme is enduring .

Options

A. Both Assertion and Reason is true and the Reason are the correct explanation of Assertion
B. Both the Assertion and the Reason are correct and the Reason is the incorrect explanation of the Aassertion
C. Assertion is true but the Reason is false
D. Both Assertion and Reason are false

The essential chemical components of many coenzymes are vitaomins, e.g., coenzyme nicotinamide adenine dinucleotide (NAD) abd NADP contain the vitamin niacin.
