A Correct answer
Explanation

Nucleus is a dense protoplasmic body that contains hereditary information for controlling cell activities as well as for transfer to next generation. The nucleus contains genetic material DNA, so it is needed for the inheritance of characters from one generation to another. Smooth endoplasmic reticulum is specialized to synthesize lipids and steroids. Ribosomes help in protein synthesis inside the cell. Plasma membrane is the outer covering of most of the animal cells, living, ultra thin, elastic, semi – permeable in nature. It provides the mechanical support and external frame to the protoplasm (cytoplasm + nucleus). Hence, the correct sequence of the codes is i - 4, ii - 3, iii - 1, iv - 2.
