B. 8 celled, 7 nucleate condition
C. 3 celled condition
D. 6 celled condition

Answer

To solve the question regarding the mature male gametophyte of Angiosperms, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Male Gametophyte**:
- The mature male gametophyte in angiosperms is represented by the pollen grain.

2. **Formation of Pollen Grain**:
- The pollen grain originates from the Pollen Mother Cell (PMC) through a process called Microsporogenesis, which involves meiosis to produce haploid microspores.

3. **Microsporogenesis**:
- In the PMC, meiosis occurs, resulting in four haploid microspores. This is the first step in the formation of the male gametophyte.

4. **Microgametogenesis**:
- Each haploid microspore undergoes mitotic division to form the pollen grain. This process is called microgametogenesis.

5. **Cell Division**:
- The microspore divides mitotically into two cells:
- A larger vegetative cell (also known as the tube cell).
- A smaller generative cell.

6. **Development of Sperm Cells**:
- The generative cell, which resides within the cytoplasm of the vegetative cell, further divides to form two sperm cells.

7. **Final Cell Count**:
- At this stage, we have:
- 1 vegetative cell.
- 2 sperm cells from the generative cell.
- Therefore, the total cell count is 3 (1 vegetative cell + 2 sperm cells).

8. **Conclusion**:
- The mature male gametophyte of angiosperms is characterized by a 3-celled condition.

### Answer:
The correct answer is **3-celled condition**.
