Solution
The correct option is D Ginkgo, Pisum
The term Spermatophyta refers to any of a group of higher plants, that produce seeds. While there are many schemes of classifying plants, on a broader level the seed plants are classified as angiosperms and gymnosperms. The gymnosperms are plants with 'naked seeds', and it is because the ovule is exposed to the environment and is not covered by a protective layer. In contrast, in angiosperms, the ovule is contained within a specialized
structure, the carpel.Ginkgo represents the gymnosperms, while Pisum (Garden pea) from the family Fabaceae correctly represents the angiosperms.
Hence the correct option is D.
