The correct option is C Gymnosperms
Gymnosperms encompass all seed plant life that is not an angiosperm. Angiosperms form flowers and therefore fruit. Gymnosperms have exposed seeds and do not flower or fruit. The name comes from the Greek word gymno, which means naked. Combined with sperm and it means naked seed or anything that has no enclosed seed structure. Cones and leaves may bear the seed and they have ovules, but they are not enclosed ovaries like those in flowers.
