Correct answer
C(A) - IV, (B) - I, (C) - II, (D) - III

Step-by-step explanation

In protein chemistry, each amino acid is assigned a one-letter code to simplify notation. The matching for the given amino acids to their one-letter codes is as follows:

  • Arginine (A) - R (IV)
  • Aspartic Acid (B) - D (I)
  • Asparagine (C) - N (II)
  • Alanine (D) - A (III)

So, the correct answer is Option C: (A) - IV, (B) - I, (C) - II, (D) - III.
