  2. B

    B and C only

  3. C

    A and C only

  4. D

    A and B only

Solution

Amino acids can be viewed as substituted methanes (statement A correct). Valine is a neutral amino acid (statement C correct).

Serine is an alcoholic (hydroxyl-containing), not aromatic, amino acid, and lysine is a basic amino acid, not acidic. Hence the correct set is A and C.
