Solution
The correct option is D Both Assertion and Reason are incorrect
Here both assertion and reason are wrong because, 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 parietal placentation has two or more longitudinal placentae that develop along the wall of a syncarpous or compound pistil.Hence, the correct answer is (D)
