Solution

The correct option is A Diadelphous stamen and marginal placentation
B. Diadelphous stamen and marginal placentation
EXPLANATION: In diadelphous stamen have 9+ 1 stamen, which are fused to form a sheath around the pistil. Marginal placentation is found in monocarpellary gynoecium. In this placentation the placentae are found along the ventral suture. We can see the marginal placentation and diadelphous stamen in the members of fabaceae family, like in alfalfa, bean, bush clover, acacia, etc.
