The correct answer is option I, II and IV.
An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms are a large group and involve shrubs, herbaceous plants, the majority of trees, and grasses. A gymnosperm refers to a plant, which has seeds unprotected by a fruit or an ovary. The gymnosperms comprise of conifers, ginkgo, and cycads.
In the given case, both the sunflower (angiosperm) and gingko (gymnosperm) are seed-producing plants. However, the seeds of a sunflower are safeguarded by a flower or a fruit, while in case of Gingkoes they are not. Also, sunflowers include double fertilization, while the Gingkoes involve only a single fertilization.
