Correct answer
DA-III, B-I, C-IV, D-II

Step-by-step explanation

The one-letter code for each amino acid is as follows:

Glutamic Acid (A) is represented by the letter E (III).

Glutamine (B) is represented by the letter Q (I).

Tyrosine (C) is represented by the letter Y (IV).

Tryptophan (D) is represented by the letter W (II).

These one-letter codes are part of the standard notation used in biology and biochemistry to represent the 20 standard amino acids, plus a few others. The codes are designed to be short and easy to remember, while still being distinct from each other.
