Answer 1

The correct option is C (iii) and (iv)

Lemon - Axile

Lemon shows the presence of axile placentation which occurs in a syncarpous pistil where the ovary is divided into multiple chambers.

The placenta occurs in the centre where the septa separating the chambers meet to form an axile column which bears the ovules.

Mustard - Parietal

Parietal placentation is seen in mustard.

In parietal placentation, placenta develops along the fused margins of adjacent carpels on the parietal wall of the ovary.

Parietal placentation occurs in a syncarpous bi or multicarpellary pistil in which the ovary is unilocular.

In mustard, a false septum or replum develops between two parietal placentae and the ovary becomes bilocular.
