The correct option is C Lemon
Axile placentation is found in multi carpellary syncarpous gynoecium. The margin of carpels growing inward, fuse and meet in the centre of the ovary. Axis forms in the centre of the ovary, thus ovary becomes multi-chambered. The ovules are borne at the central axis. The number of these chambers are equal to the number of carpels. For example, potato, china rose, onion, lemon, orange and tomato.
Therefore, the correct answer is option C.
