Assertion: Fungi prefer to grow in cold and humid areas.
Reason: Low temperature favours the metabolic activities.

Options

A. If both assertion and Reason are true and the reason is a correct explanation of the assertion.
B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion and Reason are False.

Answer

To analyze the given assertion and reason, we will follow these steps:

### Step 1: Understand the Assertion
The assertion states that "Fungi prefer to grow in cold and humid areas."

- **Analysis**: Fungi are known to thrive in a variety of environments. While some fungi can grow in cooler temperatures, the majority of fungi prefer warmer conditions, typically between 25 to 30 degrees Celsius (77 to 86 degrees Fahrenheit). Therefore, the assertion is misleading as it suggests that fungi predominantly prefer cold areas.

### Step 2: Understand the Reason
The reason states that "Low temperature favors the metabolic activities."

- **Analysis**: Metabolic activities in fungi generally increase with temperature, up to a certain optimal range. Low temperatures can slow down metabolic processes rather than enhance them. Hence, this reason is also incorrect.

### Step 3: Conclusion
Based on the analysis of both the assertion and the reason:

- The assertion is false because fungi do not prefer cold and humid areas; they thrive better in warm and moist conditions.
- The reason is also false because low temperatures do not favor metabolic activities in fungi.

### Final Answer
Both the assertion and reason are false. Therefore, the correct answer is option number four: "Both assertion and reason are false."
