The correct option is B exocarp
The pericarp or fruit seed coat is thick and fleshy. It is differentiated into three distinct layers.
The outermost layer of the pericarp is called exocarp. It is found in various colours and it is leathery in texture. It is called the skin of the fruit.
The middle mesocarp layer is the edible part of the fruit.
The inner endocarp layer is hard and fibrous.
