C

D

Explanation: 

Detailed explanation-1: -Nine amino acids-histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine-are not synthesized by mammals and are therefore dietarily essential or indispensable nutrients. These are commonly called the essential amino acids.

Detailed explanation-2: -Rice and beans are, separately, both incomplete proteins; but when they’re eaten together, they’re considered complementary proteins, according to the FDA. When consumed together, each provides the amino acids that the other lacks. Rice doesn’t have enough lysine, but beans do.

Detailed explanation-3: -Foods that contain all nine essential amino acids are called complete proteins. These foods include beef, poultry, fish, eggs, dairy, soy, quinoa and buckwheat. Foods that contain some but not all the essential amino acids are called incomplete proteins. These foods include nuts, seeds, beans and some grains.
