(C) The given amino acid is glutamic acid,which has two carboxylic acid groups and one amino group.For an acidic amino acid,the isoelectric point $(pI)$ is calculated as the average of the two lowest $pK_a$ values.$pI = \frac{pK_{a1} + pK_{a2}}{2}$$pI = \frac{2 + 4}{2} = \frac{6}{2} = 3.0$Therefore,the correct option is $C$.
