A thermometer indicates `98.6^@C` . It may be

Options

A. outdoors on a cold day.
B. in a comfortable room.
C. in a cup of hot tea.
D. in a normal person's mouth.

Answer

To solve the question "A thermometer indicates 98.6°C. It may be," we need to analyze the given temperature in the context of different scenarios.

### Step-by-Step Solution:

1. **Understanding the Temperature Scale**:
- The temperature is given in degrees Celsius (°C). It's important to differentiate this from Fahrenheit (°F), as 98.6°F is commonly known as the average human body temperature.

2. **Comparing with Human Body Temperature**:
- The average human body temperature is approximately 37°C. The value of 98.6°C is significantly higher than the normal body temperature, which indicates that this temperature is not typical for a human body.

3. **Evaluating the Options**:
- **Outdoors on a Cold Day**:
- On a cold day, outdoor temperatures typically range from about 12°C to 20°C. Since 98.6°C is much higher than this range, this option is incorrect.

- **In a Comfortable Room**:
- Comfortable room temperatures are usually around 20°C to 25°C. Again, 98.6°C is far too high for a comfortable indoor environment, making this option incorrect.

- **In a Cup of Hot Tea**:
- When tea is made, the water is usually boiled at 100°C. If the tea is freshly made and still hot, it could be around 98.6°C, making this option plausible.

- **In a Normal Person’s Mouth**:
- The normal body temperature in the mouth is around 37°C. Since 98.6°C is much higher than this, this option is also incorrect.

4. **Conclusion**:
- After evaluating all the options, the only scenario where 98.6°C is reasonable is "in a cup of hot tea."

### Final Answer:
The thermometer indicating 98.6°C may be in a cup of hot tea.
