The correct option is A Drupe
A drupe or stone fruit is an indehiscent fruit in which an outer fleshy part-exocarp, or skin and mesocarp or flesh surrounds a shell of hardened endocarp with a seed inside. These fruits usually develop from a single carpel and mostly from flowers with superior ovaries. The definitive characteristic of a drupe is that the hard, lignified stone (or pit) is derived from the ovary wall of the flower. In an aggregate fruit composed of small, individual drupes, each individual is termed as a drupelet. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes.
Thus, the correct answer is option A.
