Step-by-Step Solution

on Placentation:

  1. Basal placentation: The placenta develops at the base of the ovary (e.g., Sunflower, Marigold).
  2. Axile placentation: The placenta is axial and the ovules are attached to it in a multilocular ovary (e.g., China rose, Tomato, Lemon).
  3. Parietal placentation: The ovules develop on the inner wall of the ovary or on peripheral part (e.g., Mustard, Argemone).
  4. Free Central placentation: The ovules are borne on the central axis and septa are absent (e.g., Dianthus, Primrose).

(Note: The correct matching sequence corresponds to A-Basal(iv), B-Axile(ii), C-Parietal(i), D-Free Central(iii)).
