The correct option is
D Monoamino monocarboxylic
Alanine is an amino acid with one amino and one carboxylic group so it is a monoamino monocarboxylic. It is a hydrophobic amino acid. The alpha carbon of the alanine is optically active. The conversion of glutamate to the pyruvate by an alanine aminotransferase which leads to the formation of alanine and α-ketoglutarate.
So, the correct answer is option D.
