C

A-IV, B-III, C-II, D-I

D

A-I, B-II, C-III, D-IV

Step-by-Step Solution

:

  • Axile placentation occurs when the placenta is axial and ovules are attached to it in a multilocular ovary, as seen in China rose, tomato, and lemon .
  • Parietal placentation involves ovules developing on the inner wall of the ovary or peripheral part, as seen in Mustard and Argemone .
  • Free central placentation occurs when ovules are borne on a central axis and septa are absent, as seen in Dianthus and Primrose .
  • Basal placentation involves the placenta developing at the base of the ovary with a single ovule attached, as seen in Sunflower and Marigold .
