Hint:
The outer layer is the edible part of the fruit that is the pericarp which is the tissue that develops from the ovary wall of the flower and surrounds the seed to protect it from damage before its dispersal to the environment.

Complete answer:
The fruits are the ripened ovaries of the flower. In the fleshy fruits the edible part of the fruit is called as pericarp, which develops from the wall of ovary.
The pericarp is made up of three layers, the epicarp (outermost layer), the mesocarp (middle layer) and the endocarp (innermost layer). Depending on these layers, there are many types of fruits, one of which is a hesperidium.
A hesperidium is a modified fleshy fruit without a stone (pit) produced from a single flower having one ovary. The outer wall of hesperidium is characterized with a thick and leathery covering while inner walls become fleshy and juicy with presence of several seeds. The peel contains many oil glands in pits. However, the fleshy interior consists of separate sections containing fluid-filled vesicles that are basically specialized hair cells. Some common examples which you may have consumed are oranges, lemons, limes, grapefruit etc.

So, the correct answer option C) Hair of ovary wall.

Note:Unlike most of the other berries the peel or skin of the hesperidium is not eaten because it is tough, bitter in taste and contains many oil glands. An exception to this is the fruit kumquat, which is consumed completely.
