Answer: (D)

If both assertion and reason are false

Answer 2

In marginal placentation, one or two alternate rows of the ovules occur longitudinally along the ridge in the wall of the ovary in the area of fusion of its two margins or ventral suture. In parietal placentation two or more longitudinal placentae develop along the wall of a syncarpous or compound pistil.
