To find the correct answer, let's first clarify the concept of sound pressure. The minimum sound pressure level that the human ear can detect is known as the threshold of hearing.

### Analysis of Options
1. **20 μPa**: Commonly accepted as the threshold of hearing in air.
2. **2 μPa**: Too low to be the threshold of hearing.
3. **10 Pa**: Extremely high; far above the threshold.
4. **200 μPa**: Higher than the commonly accepted threshold.

### Final Answer
The minimum sound pressure that the human ear can detect is **20 μPa**.
