Options

  1. AA - 4, B - 2, C - 1, D - 3
  2. BA - 3, B - 4, C - 2, D - 1
  3. CA - 1, B - 3, C - 4, D - 2
  4. DA - 2, B - 1, C - 3, D - 4

Correct answer

A. A - 4, B - 2, C - 1, D - 3

Step-by-step solution

Non-polar amino acids (A) like Alanine (IV) have hydrophobic side chains. Polar amino acids (B) such as Serine (II) have hydrophilic side chains. Acidic amino acids (C) like Aspartic acid (I) have a negative charge at physiological pH. Basic amino acids (D) like Lysine (III) have a positive charge.
