C.Stony mesocarp
D.Stony endocarp

Answer 1

Hint: Drupe, in natural science, straightforward meaty organic product that generally contains a solitary seed, for example, the cherry, peach, and olive. As a basic natural product, a drupe is gotten from a solitary ovary of an individual bloom.

Complete answer:
Drupe fruit: In organic science, a natural product is the matured ovary—along with seeds—of a blooming plant. There is an extraordinarily decent variety in kinds of natural products. In natural science, a drupe is an organic product wherein an external meaty part (excerpt, or skin; and monocarpic, or tissue) encompasses a shell (the pit or with a seed inside. The external layer is a slim skin. The center layer will in general be thick and beefy, however might be sinewy (as in the coconut) or extreme. Drupe is gotten from the ovary mass of the blossom.
Other meaty natural products may have that originates from the seed coat encompassing the seed. These natural products are not drupes. The term stone natural product, or stone organic product, can be an equivalent for "drupe" or, all the more normally, it can mean only the product of the Prunes class. The coconut is a drupe, yet the monocarpic is stringy or dry (for this situation, called a husk), so this kind of natural product is named a straightforward dry natural product, sinewy drupe. In contrast to different drupes, the coconut seed is probably not going to be scattered by being gulped by fauna, because of its enormous size. It can, in any case, glide very significant distances across seas.

Hence the correct answer is option(D)
Note: The external layer of the ovary divider is a slim skin or strip, the center layer is thick and typically plump (however at times extreme, as in the almond, or stringy, as in the coconut), and the internal layer, known as the pit, or putamen, is hard and stony. The pit, which is frequently mistaken for the seed itself, as a rule has one seed or, seldom, a few, where case just one grows completely.
