Which of the following options are not a function of Ribosomes? (1) It helps in manufacture of starch grains. (ii) It helps in manufacture of hormones. (iii) It helps in manufacture of enzymes. (iv) It helps in manufacture of protein molecules.

The correct answer is (d) (i) and (ii).
Ribosomes are responsible for protein synthesis and help in the manufacture of enzymes (which are proteins). However, they do not manufacture starch grains (carbohydrates) or hormones (some of which are proteins but are synthesized in specific glands, not directly by ribosomes).
