    Answer:

    B. K – Lysine.

    Explanation:

    Required

    The easiest amino acid to distinguish

    The 4 amino acids in the question can be grouped into 2. The groups are:

    (1) Group I – Nonpolar amino acids and (2) Group IV – Basic amino acids

    Three of the amino acids belong to group I while the last belongs to group IV.

    The acids according to their categories are:

    (1) Group I – Nonpolar amino acids:- Phenylalanine, Valine and Glycine

    (2) Group IV – Basic amino acids:- Lysine

    Because Lysine belongs to a different group different from the other three, it will be easily distinguished because it will exhibit a different property from the other three acids.
