The correct answer is Three.

Here's why:

(a) Each protein is a polymer of amino acids - This is correct. Proteins are made up of amino acids linked together in a chain.

(b) A protein is a hetero polymer and not a homopolymer - This is correct. Proteins are heteropolymers because they are composed of different types of amino acids. Homopolymers are composed of only one type of monomer, which is not the case for proteins.

(c) Dietary proteins are the source of essential amino acid - This is correct. Essential amino acids are those that the body cannot synthesize on its own and must be obtained through diet. Proteins in the food we eat are broken down into amino acids, which are then used to make new proteins in the body.

(d) Collagen is the most abundant protein in whole of the biosphere - This is incorrect. Collagen is the most abundant protein in the animal kingdom, particularly in mammals, but not in the whole biosphere. In the biosphere as a whole, the most abundant protein is RuBisCO, an enzyme involved in photosynthesis in plants.
