The correct option is B Shoot
Bulbs are underground buds with the stem reduced to small discs on which short, fleshy storage leaves grow. These leaves are enclosed by thick scales. Bulb scales morphologically are the continuous sheathing leaf bases. Bulbs are produced by monocotyledons plants in which the usual structure is modified for storage and reproduction. The outer scales are generally fleshy and contain reserve food material.
Therefore, the correct option is B.
