The correct answer is: 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.
