The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Double Fertilization:** - Double fertilization is a unique reproductive process where two male gametes (sperm cells) fertilize two different structures within the female gametophyte. 2. **Identifying the Organisms:** - The question asks in which organisms double fertilization occurs. We need to evaluate the options provided. 3. **Analyzing the Options:** - **Option A: Angiosperms** - Angiosperms are flowering plants that exhibit double fertilization. In this process, one male gamete fuses with the egg cell to form a zygote (syngamy), while the second male gamete fuses with two polar nuclei to form the triploid endosperm. - **Option B: Gymnosperms** - Gymnosperms do not exhibit double fertilization; they have a different fertilization process. - **Option C: Pteridophytes** - Pteridophytes (ferns and their relatives) also do not show double fertilization. - **Option D: Bryophytes** - Bryophytes (mosses and liverworts) do not exhibit double fertilization either. 4. **Conclusion:** - Based on the analysis, double fertilization is a unique feature of angiosperms. Therefore, the correct answer is **Option A: Angiosperms**.
