Let us carefully analyze each of the options given to determine the correct match:

Option A: Gymnosperms : Cedrus, Pinus, Sequoia

Explanation: Gymnosperms are a group of seed-producing plants that include conifers, cycads, Ginkgo, and gnetophytes. Both Cedrus (cedars), Pinus (pines), and Sequoia (redwoods) belong to the gymnosperms. Thus, the match is correct.

Option B: Angiosperms : Wolffia, Eucalyptus, Sequoia

Explanation: Angiosperms are flowering plants. While Wolffia (smallest flowering plant) and Eucalyptus are angiosperms, Sequoia is a gymnosperm. Hence, this match is incorrect.

Option C: Bryophytes : Polytrichum, Polysiphonia, Sphagnum

Explanation: Bryophytes are non-vascular plants like mosses and liverworts. While Polytrichum and Sphagnum are indeed bryophytes, Polysiphonia is a red algae (Rhodophyta) and not a bryophyte. Thus, this match is incorrect.

Option D: Pteridophytes : Equisetum, Ginkgo, Adiantum

Explanation: Pteridophytes are a group of vascular plants that reproduce via spores. Equisetum (horsetails) and Adiantum (maidenhair ferns) are pteridophytes, but Ginkgo is a gymnosperm. Hence, this match is incorrect.

Therefore, the correct match is:

Option A: Gymnosperms : Cedrus, Pinus, Sequoia
