The correct answer is option A
Algae, mosses, and ferns.
- Ferns, algae, and bryophytes(mosses) need water for the movement of male gametes towards the female gamete.
- So these three organisms of the kingdom Plantae depend on external sources of free water for fertilization.
- Algae belong to a group of living things called protists but they are neither plants nor animals instead, they are photosynthetic organisms and can be either unicellular or multicellular.
- Mosses are nonflowering plants with stems and leaves but they do not have true roots.
- Ferns are also nonflowering vascular plants bearing true roots.
- Gymnosperms are not enclosed in an ovary since they are seed-bearing plants.
