(B) Amino acids are classified based on the nature of their $R$ group.$1$. Basic amino acids contain an extra amino group in their side chain,making them positively charged at physiological $pH$. Examples include $Lysine$,$Arginine$,and $Histidine$.$2$. Acidic amino acids contain an extra carboxyl group in their side chain,making them negatively charged. Examples include $Glutamic$ $acid$ and $Aspartic$ $acid$.$3$. Glycine and Alanine are neutral amino acids.Therefore,$Lysine$ and $Arginine$ are basic amino acids.
