Options
- A(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- B(A)-(I), (B)-(III), (C)-(IV), (D)-(II)
- C(A)-(III), (B)-(I), (C)-(II), (D)-(IV)
- D(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Correct answer
D. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
Step-by-step solution
Marginal placentation is found in Pea, where the placenta forms a ridge along the ventral suture of the ovary. Parietal placentation is seen in Mustard, where ovules develop on the inner wall of the ovary. Free central placentation is observed in Dianthus, where ovules are borne on a central axis and septa are absent. Basal placentation is found in Sunflower, where a single ovule is attached to the placenta at the base of the ovary. Therefore, the correct match is (A)-(III), (B)-(I), (C)-(IV), (D)-(II). Answer: (A)
