The correct option is A Perianth and peduncle
Sorosis is a fleshy multiple fruit, such as that of the pineapple and mulberry, formed from flowers that are crowded together on a fleshy stem. The edible part is actually perianth and peduncle. A multiple fruit is a fruit that develops from the merger of several ovaries that were separate in a single flower. The sheath or the perianth, of the inflorescence around the seed in the inflorescence is the edible part of the sorosis. It is a yellow shiny part. The perianth is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx and the corolla.
Thus, the correct answer is option A.
