Solution
The correct option is DCedrus Cedrus is a gymnosperm having reduced dependent gametophytes- pollen and endosperm. In gymnosperms the male and the female gametophytes do not have an independent free-living existence and remain within the sporangia and are retained on the sporophytes. Hence, option D is correct.
