The correct option is A Pear - mesocarp and endocarp
The edible part of mesocarp and endocarp. Pear is an accessory fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel. The fruit of pear is composed of the receptacle or upper end of the flower-stalk greatly dilated. Enclosed within its cellular flesh is the true fruit, five cartilaginous carpels, known colloquially as the core. From the upper rim of the receptacle are given off the five sepals the five petals, and the very numerous stamens.
Thus, the correct answer is option A.
