Answer 1

1.Proteins from plant sources:

Animal proteins are considered as high-quality proteins because their amino acid composition matches that needed to synthesize body protein. Plant proteins are considered as incomplete proteins because most plants proteins are limited in one or more of the essential amino acids needed to make body protein. The protein quality of plant protein is improved by complementation. Complementation combines proteins with different limiting amino acids to supply enough of all the essential amino acids. Thus we can say that Proteins from plant sources can be combined to obtain complementary proteins

Thus here the answer is Option "c "can be combined to obtain complementary proteins.
