Solution
The correct option is C diadelphous condition
Aestivation refers to the arrangement of sepals or petals within a flower in bud condition.
Vexillary aestivation is a characteristic feature of the family Fabaceae. In vexillary aestivation, there are five petals, one large standard petal overlapping the two wing petals.
These in turn overlap the two small keel petals.
Family Fabaceae also show diadelphous condition. Diadelphous condition means there are a total of 10 stamens in a flower of which the filaments of 9 stamens are united into one bundle and 10th stamen remains free.
Epipetalous condition is a feature of the plants of Solanaceae. The filaments of stamens are attached to the petals.
The arrangement of ovules inside the ovary is called placentation. Members of Fabaceae show marginal placentation.
In marginal placentation, the placenta develops along the ventral suture of the ovary and ovules are attached to placenta in two rows.
In axile placentation, the ovary is multilocular and the placenta is axial and ovules are attached to it.
The fruit in Fabaceae is legume. Legume is a dry dehiscent fruit. E.g. Pea.
Berry is a fleshy fruit. E.g. Tomato, brinjal.
