B Correct answer
Explanation

A hesperidium is a modified berry with a tough, leathery rind. The peel contains volatile oil glands in pits. The fleshy interior is composed of separate sections, called as carpels, filled with fluid-filled vesicles that are actually specialized hair cells. The outer ovary wall becomes the thick spongy layer of the rind, while the inner ovary wall becomes very juicy with several seeds. Thus, orange is a hesperidium, in this fruit the endocarp projects inwards forming distinct chambers and epicarp and mesocarp fuse to form the separable part. 

Thus, the correct answer is option B.
