(b) and (c)
B
Correct answer
Explanation
Marginal placentation (a) develops from bicarpellary, syncarpous ovary that becomes unilocular (as in Fabaceae). Parietal placentation (c) develops from multicarpellary, syncarpous, unilocular ovary where ovules attach to the ovary wall. Basal placentation (d) develops from bicarpellary, syncarpous, unilocular ovary with single ovule at base. Axile placentation (b) requires multilocular ovary, not unilocular.
