B. 6- 12 times/min
C. 10- 24 times/min
D. 12- 16 times/min

Answer

To determine the normal breathing rate of a healthy man, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Breathing Rate**:
- Breathing rate refers to the number of breaths taken in one minute. It is an important physiological parameter that can indicate the health status of an individual.

2. **Identify the Normal Range**:
- The normal breathing rate for a healthy adult is typically measured in breaths per minute.

3. **Evaluate the Options Provided**:
- The question provides four options:
- A) 8-18 times per minute
- B) 6-12 times per minute
- C) 10-24 times per minute
- D) 12-16 times per minute

4. **Recall the Normal Breathing Rate**:
- Based on physiological studies, the normal breathing rate for a healthy adult male is approximately 12 to 16 breaths per minute.

5. **Analyze Each Option**:
- A) 8-18 times per minute: This range includes lower values that are not typical for a healthy adult.
- B) 6-12 times per minute: This is below the normal range.
- C) 10-24 times per minute: This range is too broad and includes values that are higher than normal.
- D) 12-16 times per minute: This matches the established normal range.

6. **Select the Correct Answer**:
- Based on the analysis, the correct answer is **D) 12-16 times per minute**.

### Final Answer:
The breathing rate of a normal healthy man is **12-16 times per minute**.
