Answer 1

The correct option is B A-$3$, B-$1$, C-$4$, D-$2$

In the family Caryophyllaceae, The ovary is unilocular and shows the free-central type of placentation. In this type, the ovules are arranged on the central axis which is not attached to the wall of the ovary by any septum. The ovules are campylotropous. Hence, the correct answer is 'Free-Central'

Solanaceae shows axile placentation. In axile placentation, the placenta is axial and ovules are attached to it.

Caesalpiniaceous shows marginal placentation, where ovules borne on the wall along the ventral suture of a simple ovary. ventral placentation.

Papaveraceae shows parietal placentation, where ovules develop on the wall or slight outgrowths of the wall forming broken partitions within a compound ovary

Hence, the correct a answer is (B)
