D) Both (a) and (b)
Correct Answer: D
Solution :
[d] It is a compound that is formed by the combination of oxygen, carbon, hydrogen, nitrogen and sometimes sulphur. Proteins are the basic constituents of our cells. They are large molecules, so they cannot get directly into our blood. Thus, they are turned into amino acids by our digestive system. They help in formation of new tissues, repair the broken tissues, regulate balance of water and acids, transport oxygen and nutrients and make antibodies. Due to these reasons they are called nitrogenous food and body building food.
