Right answer is (b) Essential Amino Acids
To explain I would say: A protein is a long chain of various amino acids which may or may not be needed by the body. Since proteins are the building blocks of the body, doing away with proteins cannot be done however taking proteins will harm the damaged kidney. In such cases, essential amino acids are ingested instead of taking in proteins. These essential amino acids are directly absorbed by the body. This allows the body to function normally and the pressure on the kidney is kept at the minimum.
