The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Male Gametophyte Formation**: The male gametophyte in angiosperms is formed from the microspore mother cell, which is diploid (2n). 2. **Meiosis**: The microspore mother cell undergoes meiosis to produce haploid microspores. This process results in the formation of a microspore dyad (two haploid microspores). 3. **Further Division**: The microspore dyad undergoes meiosis II, which is similar to mitosis, leading to the formation of a microspore tetrad (four haploid microspores). 4. **Dissociation of Microspores**: The microspore tetrad dissociates, resulting in four individual haploid microspores. 5. **Mitotic Division of Microspore**: Each microspore undergoes mitotic division. This division produces two types of cells: one vegetative cell and one generative cell. 6. **Further Division of Generative Cell**: The generative cell undergoes another mitotic division, resulting in two male gametes. 7. **Final Count of Cells**: After all divisions, the final structure of the male gametophyte consists of one vegetative cell and two male gametes, totaling three cells. 8. **Conclusion**: Therefore, the male gametophyte of angiosperms is reduced to three cells. **Final Answer**: The male gametophyte of angiosperms is reduced to three cells. ---
