Answer

To determine which option represents male gametes, let's analyze each option step by step:

1. **Understanding Gametes**:
- Gametes are the reproductive cells that unite during sexual reproduction to form a new organism. In flowering plants, male gametes are produced in the male reproductive structures.

2. **Analyzing the Options**:
- **A. Antipodals**: These are part of the female gametophyte in plants and do not represent male gametes.
- **B. Synergids**: These are also part of the female gametophyte and assist in the fertilization process, but they are not male gametes.
- **C. Endosperm**: This is a tissue that nourishes the developing embryo and is formed after fertilization. It contains genetic material from both male and female gametes but is not a gamete itself.
- **D. Pollen grains**: These are the male gametes in flowering plants. They are produced in the anthers of the stamen and are responsible for fertilizing the ovule.

3. **Conclusion**:
- Based on the analysis, the option that represents male gametes is **D. Pollen grains**.

### Final Answer:
The correct answer is **D. Pollen grains**.
