Galactosemia is a metabolic disorder where the body cannot break down galactose. Avoiding milk and dairy products, which contain lactose (a source of galactose), prevents the accumulation of toxic metabolites.

Skin pigmentation is determined by the amount and type of melanin produced by specialized cells called melanocytes.

• Here, option (C) is correct as Galactosemia is metabolic genetic metabolic disorder due to deficiency of the enzyme uridyl transferase.

Glutamine and Glycine are not basic amino acids. Only Arginine and Histidine are basic amino acids. Histidine is weakly charged under physiological ph. Hence, Arginine is the most basic amino acid. 

Hemoglobin has four chains: two alpha chains and two beta chains with heme and iron part along with oxygen. There are some hydrophobic substances (water-hating) present on the surface of proteins. These hydrophobic residues forms cluster and pocket-like structure on the surface of beta chains. These pockets are responsible for diseases like sickle cell anemia also in the beta chain the position of glutamic acid at sixth place in the chain is replaced by valine leading to the shape of red blood cells to be sickle-like due to loss of oxygen.
