The correct answer is D)it is a seeded vascular plant. What this means is that it is a Gymnosperm, which is why it has a cone. The cones have the seeds in it and when the cones open the seeds fall down and spread. Basically, the seeds are unprotected, also known as "naked", and they form on leaves or similar things and turn into cones.
