Best answer
Correct answer is (b) root hairs

To explain I would say: Control points or transport proteins are present in endodermal cells of the plant system. Root hairs arise from region of maturation of the root system. They help in increasing area for absorption. Epidermal cells and the cortical cells allow both apoplastic and symplastic pathway.
