D. `2n,2n,n,2n,2n,2n`

Answer

To determine the correct ploidy levels for the ovary, anther, egg, pollen, male gamete, and zygote, we will analyze each structure step by step:

1. **Ovary**:
- The ovary is the female reproductive part of the plant that contains ovules. It is a diploid structure because it is formed from the fusion of two gametes during fertilization.
- **Ploidy**: 2n (diploid)

2. **Anther**:
- The anther is part of the male reproductive structure of the flower and produces pollen grains. It is also a diploid structure as it develops from the sporophyte generation.
- **Ploidy**: 2n (diploid)

3. **Egg**:
- The egg, also known as the ovule, is the female gamete found within the ovary. Being a gamete, it is haploid.
- **Ploidy**: n (haploid)

4. **Pollen**:
- Pollen grains are the male gametes produced by the anther. Like the egg, pollen grains are also haploid.
- **Ploidy**: n (haploid)

5. **Male Gamete**:
- The male gamete is represented by the pollen grain. Therefore, it is also haploid.
- **Ploidy**: n (haploid)

6. **Zygote**:
- The zygote is formed when the male and female gametes (pollen and egg) fuse together. This fusion results in a diploid cell.
- **Ploidy**: 2n (diploid)

Now, summarizing the ploidy levels:
- Ovary: 2n
- Anther: 2n
- Egg: n
- Pollen: n
- Male Gamete: n
- Zygote: 2n

### Final Answer:
- Ovary: 2n
- Anther: 2n
- Egg: n
- Pollen: n
- Male Gamete: n
- Zygote: 2n
