Identify the different types of placentations shown in figure and select the correct option.
A is marginal placentation. In marginal placentation the placenta forms a ridge along the ventral surface of the ovary and the ovules are borne on this ridge forming two rows, as in pea.
B is basal placentation. In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it, as in sunflower and marigold.
C is axile placentation. In axile placentation, ovules are borne at or around the center of a compound ovary on an axis formed from joined septa., as in china rose, tomato and lemon.
D is free central placentation. In free central placentation, the ovules are borne on central axis and septa are absent, as in Dianthus and primrose.
E is parietal placentation. In parietal placentation, the ovules develop on the inner wall of the ovary or on peripheral part. Ovary is one-chambered but it becomes two chambered due to the formation of the false septum, e.g., mustard.
