An archean that lives in extremely salty condition is referred to as a-

Options

A. Thermophile
B. Halophiles
C. Thermoacidophile
D. Methanogen

Answer

To solve the question about the type of archean that lives in extremely salty conditions, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the specific type of archean that thrives in extremely salty environments.

2. **Identify Archeans**: Archeans are a group of single-celled microorganisms that are distinct from bacteria and eukaryotes. They are known for living in extreme environments.

3. **Recognize Extreme Conditions**: Archeans can be found in various extreme conditions, such as high temperatures (thermophiles), high acidity (acidophiles), and high salinity (halophiles).

4. **Focus on Salinity**: Since the question specifically mentions "extremely salty conditions," we need to identify which archeans are adapted to high salt concentrations.

5. **Identify the Correct Term**: The archeans that live in salty environments are known as "halophiles." This term comes from "halo," meaning salt, and "phile," meaning lover of.

6. **Conclusion**: Therefore, the archean that lives in extremely salty conditions is referred to as a "halophile."

### Final Answer:
The correct answer is **halophile**.
