A) marginal
B) basal
C) free central
D) axile
Correct Answer: B
Solution :
In basal placentadon, ovary is bicarpellary, syncarpous and unilocular and a single ovule is borne at the base of ovary, eg, marigold. In marginal placentation, the ovary is simple, unilocular and the ovules are arranged along the margin of the unilocular ovary, eg, pea. In free central placentation, ovary is unilocular and the placenta bearing ovules are "arised from the central axis, eg, Stellaria. In axile placentadon, ovary is two or more chambered, usually as many as the number of carpels, eg. Petunia.
