Solution
The correct option is B Orchid
The aerial roots of plants absorb moisture from the air. These roots are seen in epiphytes which grow on the surface of other plants. Epiphytic plants take nutrition from air, rain and surrounding organic debris, as they are not in contact with soil. Orchids are epiphytes which have aerial roots with a modified spongy layer of the epidermis called velamen which can absorb moisture from humid air. The cells of velamen absorb water during rains and store for future.Option B is correct
