Solution
The correct option is C parietal
The arrangement of ovules in the ovary is called placentation. The ovary is made up of chambers called as locules in which the ovules are attached.
Parietal placentation : The ovules develop on the inner wall of the ovary or on peripheral parts, as seen in Cucurbita.
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, as in china rose, tomato and lemon
Basal placentation: When one or few ovules develop at the base of a simple or compound ovary as seen in tomatoes.
Free Central : The ovules are borne on the central axis and septa are absent. It is seen in primrose and Dianthus.
Marginal placentation : The ovules are arranged in two rows on the margins of the ovary as seen in pea.
