Detailed explanation-1: -Placentation is the arrangement of ovules inside the ovary. When ovules develop on the inner wall or peripheral part of the ovary, it is called parietal placentation.

Detailed explanation-2: -Definitions of parietal placentation. where ovules develop on the wall or slight outgrowths of the wall forming broken partitions within a compound ovary. type of: placentation. arrangement of the ovules in the placenta and of the placentas in the ovary.

Detailed explanation-3: -The placentation is parietal in brassica because the ovary is bicarpellary or rarely multicarpellary, syncarpous, unilocular but becomes bilocular due to the formation of false septum called replum. So, the correct answer is ‘Brassica’.

Detailed explanation-4: -Unilocular ovaries with single ovule show basal or apical placentation.

Detailed explanation-5: -Primrose has free-central placentation where the ovules are borne around a central column, which is not connected with the ovary wall by any septum.
