- D.China rose, Petunia and Lemon✓
Correct Answer
(D) China rose, Petunia and Lemon
Solution & Explanation
In axile placentation the placenta is axial and ovules are attached to it in a multilocular ovary, as in china rose, tomato and lemon. Option D (China rose, Petunia and Lemon) lists three axile examples (Petunia, a Solanaceae member, also has axile placentation). The distractors mix parietal (mustard), marginal (beans, pea) and free-central (Dianthus, Primrose) types, so D is correct. NCERT Reference: Ch 5, p.65, lines 29-31 — "said to be axile, as in china rose, tomato and lemon"
