Solution

Family Solanaceae (brinjal, potato, tomato, Petunia) has a bicarpellary, syncarpous, superior ovary.
The ovary is placed obliquely, i.e. the septum is not in the median plane of the flower, and the placenta is swollen with many ovules (axile placentation).
Mustard (Cruciferae) has a bicarpellary ovary but it is not oblique; Pisum has a monocarpellary ovary; banana has a tricarpellary inferior ovary.
So a bicarpellary gynoecium with an oblique ovary occurs in brinjal.
