Coenocytic condition is found in

Options

A. Ulothrix
B. Chlamydomonas
C. Spirogyra
D. Vaucheria.

Answer

**Step-by-Step Solution:**

1. **Understanding Coenocytic Condition**:
- Coenocytic condition refers to a multinucleate cell that results from multiple nuclear divisions without the accompanying division of the cytoplasm (cytokinesis). This leads to a single cell containing multiple nuclei.

2. **Analyzing the Options**:
- **A. Eulothrix**: This is a green alga, typically unicellular or filamentous but does not exhibit coenocytic conditions.
- **B. Chlamydomonas**: This is a unicellular green alga that has a single nucleus, thus it does not exhibit coenocytic conditions.
- **C. Spirogyra**: This is a filamentous green alga that has a filamentous structure with cells containing one nucleus each, so it does not exhibit coenocytic conditions.
- **D. Vacheria**: This organism is known to exhibit a coenocytic condition, as it has a multinucleate structure.

3. **Conclusion**:
- Based on the analysis of the options, the organism that exhibits coenocytic condition is **D. Vacheria**.

**Final Answer**: D. Vacheria
