The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Gymnosperms**: Gymnosperms are a group of plants characterized by having naked seeds, meaning their ovules are exposed and not enclosed within an ovary wall. 2. **Pollination Process**: In Gymnosperms, pollination is the transfer of pollen grains (male gametophytes) to the female reproductive structure, known as the archegonia. 3. **Production of Spores**: Gymnosperms are heterosporous, producing two types of spores: microspores (which develop into pollen grains) and megaspores (which develop into the female gametophyte). 4. **Release of Pollen**: The pollen grains are formed in microsporangia and are released into the environment. 5. **Mechanism of Pollination**: The primary mechanism for the transfer of pollen grains in Gymnosperms is through wind. The pollen grains are carried by air currents until they reach the archegonia. 6. **Fertilization**: Once the pollen grains come into contact with the archegonia, they discharge their contents, allowing fertilization to occur, leading to the formation of a zygote and eventually an embryo. 7. **Conclusion**: Therefore, in Gymnosperms, the main agent of pollination is wind. **Final Answer**: In Gymnosperms, pollination takes place primarily by wind. ---
