Correct option is C
The correct answer is
(c) Stem.
· A potato is a tuber, which is a modified stem that grows underground. It stores nutrients for the plant.
· True roots grow downward from the plant and absorb water and nutrients from the soil. Potatoes don't perform this function.
· Buds are small structures on a plant that can develop into new stems, leaves, or flowers. Potatoes do have "eyes" that contain buds, but the potato itself is not a bud.
· Fruits develop from the flower of a plant and contain seeds for reproduction. Potatoes don't develop from flowers and aren't fruits.
