Answer 1

The correct option is C

If assertion is true but reason is false

In opposite phyllotaxy, two leaves are borne on the opposite sides of a single node. E.g., Quisqualis (opposite and superposed) and Calotropis (opposite and decussate). Nerium or Oleander shows whorled type of phyllotaxy and China rose exhibits alternate phyllotaxy.
