Solution

The correct option is C Assertion is correct but Reason is incorrect.
The family Fabaceae, is commonly known as the legume, pea, or bean family and consists mostly of a genera that are agriculturally important food plants. The plants have unicarpelate, superior ovary with marginal placentation. The type of placentation is not the reason for ovary being monocarpellary.
Therefore, the correct option is C.
