The hearing range of human ear is

Options

A. 20 Hz to 20, 000 Hz
B. less than 20 Hz
C. more than 20,000 Hz
D. 20,00 Hz to 25,000 Hz

Explanation

To solve the question regarding the hearing range of the human ear, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the hearing range of the human ear, which is the range of frequencies that humans can hear.

2. **Identifying the Options**: The options provided are:
- Option 1: 20 Hz to 20,000 Hz
- Option 2: Less than 20 Hz
- Option 3: More than 20,000 Hz
- Option 4: 2000 Hz to 25,000 Hz

3. **Defining Hearing Range**: The typical hearing range for humans is known to be between 20 Hz (low frequency) and 20,000 Hz (high frequency). This range is often referred to as the "audible range."

4. **Analyzing Each Option**:
- **Option 1 (20 Hz to 20,000 Hz)**: This matches the known hearing range of humans.
- **Option 2 (Less than 20 Hz)**: This frequency range is known as infrasonic sound, which is not audible to humans.
- **Option 3 (More than 20,000 Hz)**: This frequency range is known as ultrasonic sound, which is also not audible to humans.
- **Option 4 (2000 Hz to 25,000 Hz)**: This range does not encompass the full audible range and includes frequencies that are not audible.

5. **Conclusion**: Based on the analysis, the correct answer is **Option 1: 20 Hz to 20,000 Hz**. This is the hearing range of the human ear.

### Final Answer:
The hearing range of the human ear is **20 Hz to 20,000 Hz**.
