Solution
The correct option is A Meristematic zone
The root is covered at the apex by a protective structure called the root cap. Just above the root cap is the zone of meristematic activity. The cells of this zone keep dividing to add new cells. The region of elongation is above the meristematic zone. The cells here have stopped dividing but undergo elongation to increase the length of the root. The next zone is the region of maturation. No change happens in the cells of this region. From this region, root hairs arise, which increase the surface area of the root and facilitate the absorption of water and minerals from the soil.
