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 need to understand the basic concepts of haploid (N) and diploid (2N) cells in plants.

### Step-by-Step Solution:

1. **Identify the Ploidy of the Ovary:**
- The ovary is part of the female reproductive structure in flowering plants and contains ovules. The cells in the ovary are diploid (2N) because they contain two sets of chromosomes.
- **Ploidy of Ovary: 2N**

2. **Identify the Ploidy of the Anther:**
- The anther is part of the male reproductive structure and produces pollen grains. The cells in the anther are also diploid (2N).
- **Ploidy of Anther: 2N**

3. **Identify the Ploidy of the Egg:**
- The egg cell is produced in the ovule and is a female gamete. It is haploid (N) because it contains one set of chromosomes.
- **Ploidy of Egg: N**

4. **Identify the Ploidy of Pollen:**
- Pollen grains are the male gametes produced by the anther. They are also haploid (N).
- **Ploidy of Pollen: N**

5. **Identify the Ploidy of Male Gametes:**
- Male gametes are synonymous with pollen grains in flowering plants. Therefore, they are haploid (N).
- **Ploidy of Male Gamete: N**

6. **Identify the Ploidy of the Zygote:**
- The zygote is formed when the male gamete (pollen) fertilizes the female gamete (egg). The zygote is diploid (2N) because it contains two sets of chromosomes, one from each parent.
- **Ploidy of Zygote: 2N**

### Summary of Ploidy Levels:
- Ovary: 2N
- Anther: 2N
- Egg: N
- Pollen: N
- Male Gamete: N
- Zygote: 2N

### Correct Option:
Based on the above analysis, the correct option for the ploidy levels is:
- **Option 2: 2N, 2N, N, N, N, 2N**
