Option (a) represents axile placentation as seen in China rose. It is a type of placentation, which occurs in syncarpous pistils. Ovary is partitioned into $2$ or more chambers. Placentae occur in the central region where the septa meet so that an axile column bearing ovules is formed. In China rose, ovary is pentalocular.
