Options
- A(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
- B(A)-(III), (B)-(II), (C)-(I), (D)-(IV)
- C(A)-(IV), (B)-(I), (C)-(II), (D)-(III)
- D(A)-(III), (B)-(I), (C)-(II), (D)-(IV)
Correct answer
D. (A)-(III), (B)-(I), (C)-(II), (D)-(IV)
Step-by-step solution
Cleistogamous flowers do not open at all, ensuring strict autogamy and producing an assured seed set even in the absence of pollinators. Hence, (A) matches with (III). Geitonogamy involves the transfer of pollen to another flower of the same plant; it requires a pollinating agent (functionally cross-pollination) but the pollen comes from the same plant (genetically similar to autogamy). Hence, (B) matches with (I). Xenogamy is the transfer of pollen to a different plant, which is the only type of pollination that b
