A Caryopsis
B Hesperidium
C Sorosis
D Syconus

Detailed Solution

Hypanthodium is the inflorescence of fig ($Ficus$): the receptacle forms a hollow, flask-shaped cavity with an apical opening, and the flowers are borne on its inner wall.
The whole inflorescence develops into a composite (multiple) fruit in which the fleshy receptacle encloses many small achenes; this fruit is called a syconus.
Sorosis is the composite fruit that develops from a spike, spadix or catkin (mulberry, pineapple, jackfruit).
Caryopsis is the one-seeded fruit of grasses, and hesperidium is the fruit of citrus.
Hence the fruit developed from a hypanthodium is a syconus.
