E)megasporangium and food supply.

Accepted Answer

Gymnosperm seeds have a sporophyte embryo, a food supply (usually in the form of a female gametophyte), and a protective seed coat. Choice A is incorrect because it does not mention the food supply. Choice C is incorrect because it describes a pollen grain, not a gymnosperm seed. Choice D is incorrect because it describes the parts of an ovule, not a gymnosperm seed. Choice E is incorrect because it only mentions the megasporangium and not the other components of the seed.
