Options

A. (a) `3800`
B. (b) `38,000`
C. (c) `380,000`
D. (d) `3,800,000`

Answer

To solve the question about the number of K-40 atoms that explode in the human body every second, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**:
- K-40 (Potassium-40) is a radioactive isotope of potassium and is the largest source of natural radioactivity in animals, including humans.

2. **Know the Average Potassium Content in the Human Body**:
- The average human body contains approximately 140 grams of potassium.

3. **Identify the Radioactive Decay of K-40**:
- Potassium-40 undergoes radioactive decay, which means that a certain number of K-40 atoms will decay (or "explode") every second.

4. **Determine the Number of K-40 Atoms**:
- Based on the information provided, it is stated that approximately 38,000 K-40 atoms explode in the human body every second.

5. **Select the Correct Answer**:
- Therefore, the correct answer to the question regarding the number of K-40 atoms that explode in the human body every second is 38,000.

### Final Answer:
The number of K-40 atoms that explode in the human body every second is approximately 38,000.
