Which one pair of examples will correctly represent the grouping Spermatophyta according to one of the schemes of classifying plants:
Spermatophyta, a category encompassing seed-bearing plants, comprises two major groups gymnosperms and angiosperms. Acacia and sugarcane fall within the category of angiosperms, while Pinus and Cycas are classified as gymnosperms. Notably, Rhizopus belongs to the fungal kingdom, whereas Triticum is categorized as an angiosperm. Ginkgo is a gymnosperm, which differentiates it from Pisum (pea), an angiospermic plant. In summary, Rhizopus is a fungus, Triticum is an angiosperm, and Ginkgo is a gymnospermic plant.
So, the correct option is (D): Ginkgo, Pisum
