Solution
The correct option is B Thorn
Thorns are modified branches or stems. Thorns are derived from shoots, they can be branched and they can have leaves. They arise from a bud. Thorns have vascular bundles inside. Spines are derived from leaves and have vascular bundles inside. Spines are modified leaves, stipules or parts of leaves, such as extensions of leaf veins. Prickles are like coarse hairs. They are extensions of the cortex and epidermis. Prickles do not have vascular bundles inside, so they can be removed more easily.
Thus, the correct answer is option B.
