The correct option is
C Axile, basal, parietal, free central
The arrangement of ovules in the ovary is called placentation.
Axile placentation: When the placenta is axial and the ovules are attached to it in a multilocular ovary, the placentation is said to be axile. For example, china rose, tomato and lemon.
