An example of axile placentation is

  1. Dianthus
  2. lemon
  3. marigold
  4. Argemone

Answer

(2) lemon

Solution

As per NCERT, when the placenta is axial and the ovules are attached to it in a multilocular ovary, the placentation is axile, as in china rose, tomato and lemon.

∵ Dianthus has free central, marigold (sunflower family) has basal and Argemone has parietal placentation,

∴ lemon shows axile placentation.
