Explanation:
Protein are macromolecules which have long chains of amino acids and they are used in the production of enzymes and aids metabolic activities of the body such as in the repair of worn out tissues and building up of muscle mass.
Protein is unique as it contains about 20 different amino acids. Carbohydrates also have Oxygen present in their compound. Calcium is the mineral responsible for building up of bones and teeth.

Metabolism, respiration and digestion are all complex chemical processes involving many steps, happening in 3 dimensional space within cells. Metabolism is the breaking of bonds within food molecules (like sugar) to harness energy for cellular work; respiration involves moving oxygen and carbon dioxide gases between cells to facilitate cellular metabolism and digestion involves breaking down food macro structures into smaller units suitable for metabolism.
So the answer is D - each of the three process involve multiple chemical reactions.
