Answer: (C)

Verified step by step guidance

1. Step 1: Understand the temperature preferences of different types of microorganisms. Microorganisms are classified based on the temperature range in which they grow best.
2. Step 2: Define Psychrophiles as microorganisms that grow optimally at cold temperatures, typically below 15°C.
3. Step 3: Define Halophiles as microorganisms that thrive in high salt concentrations, not necessarily related to temperature or moisture.
4. Step 4: Define Thermophiles as microorganisms that grow best at high temperatures, usually above 45°C.
5. Step 5: Define Mesophiles as microorganisms that grow optimally at moderate temperatures, generally between 20°C and 45°C, which corresponds to warm, moist environments.
