The correct option is A Parenchyma
Parenchyma is living cells which can be categorised as simple meristematic tissue. They have a thin cell wall made up of cellulose. The cytoplasm is vacuolated with a prominent nucleus. They have large central vacuoles, which allow the cells to store and regulate ions, waste products and water. Tissue specialised for food storage is commonly formed of parenchyma cells. Thus, option A is correct.
