The correct option is C Perianth and peduncle
A sorosis is a type of multiple or composite fruit which develops from spike or spadix or catkin, where the fleshy and juicy part is formed from the axis, the bract and the perianth. The perianth and fleshy peduncle are edible and enclose a bladder-like fruit with a single large seed, e.g., Jackfruit.
Thus, the correct answer is option C.
