  1. ABoth A and R are individually true and R is the correct explanation of A
  2. BBoth A and R are individually true but R is not a correct explanation of A
  3. CA is true but R is false
  4. DA is false but R is trueCorrect

Explanation

The correct answer is D because the Assertion is false while the Reason is true. The Assertion is false because Glycerine, Serine, and Tyrosine are non-essential amino acids. This means the human body can synthesize them internally, so they do not compulsorily need to be included in the diet. The Reason is true because essential amino acids are those that the human body cannot produce on its own. Therefore, they must be obtained through food sources. Since the specific substances mentioned in the Assertion are not essential amino acids, the statement in the Assertion is incorrect.
