The Correct Option is A

Solution and Explanation

In marginal placentation, one or two alternate rows of ovules occur longitudinally along the ridge in the wall of the ovary in the area of fusion of its two margins or ventral suture. A true placenta is believed to be absent. Ovary is unilocular. Marginal placentation is found in monocarpellary pistils of Leguminosae (e.g., Pea, Cassia, Acacia) and other plants (e.g., Larkspur).
