The C-terminal group refers to the terminal carboxyl group (-COOH) of an amino acid. In the given protein sequence, lysine (K) is at the C-terminus as it has the carboxyl group at its end. Asparagine (N), phenylalanine (F), and cysteine (C) do not have the carboxyl group at their end and therefore cannot be the C-terminal amino acid.
