Answer 1

The human body requires 9 essential amino acids for proper functioning, which cannot be synthesized by the body and must be obtained through the diet. These are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, theronine, tryptophan, and valine. Therefore, none of the options provided (8, 20, 5, 12) are correct in the context of the number of essential amino acids.
