Which of the following frequencies does not belong to FM broadcast.

Options

A. `64MHz`
B. `106MHz`
C. `99MHz`
D. `89MHz`

Answer

To determine which frequency does not belong to the FM broadcast range, we need to know the standard frequency range for FM radio.

### Step-by-Step Solution:

1. **Identify the FM Broadcast Frequency Range**:
The FM broadcast range is typically from 88 MHz to 108 MHz. This means any frequency below 88 MHz or above 108 MHz does not belong to FM broadcasting.

2. **Examine the Given Frequencies**:
We need to look at the options provided in the question. For this example, let’s assume the options include:
- Option 1: 64 MHz
- Option 2: 89 MHz
- Option 3: 99 MHz
- Option 4: 106 MHz

3. **Compare Each Frequency Against the FM Range**:
- **Option 1: 64 MHz** - This frequency is below 88 MHz, so it does not belong to the FM broadcast range.
- **Option 2: 89 MHz** - This frequency is within the FM range (88 MHz to 108 MHz).
- **Option 3: 99 MHz** - This frequency is also within the FM range.
- **Option 4: 106 MHz** - This frequency is within the FM range as well.

4. **Conclusion**:
Since 64 MHz is the only frequency that falls outside the FM broadcast range, it is the correct answer.

### Final Answer:
**Option 1: 64 MHz does not belong to FM broadcast.**
