C. 30 KHz to 300 KHz
D. 3 GHz to 30 GHz

Answer

To determine the FM radio broadcasting band, we need to analyze the provided options and identify the correct frequency range.

### Step-by-Step Solution:

1. **Understand the Options**: The question provides four frequency ranges:
- A) 5 MHz to 30 MHz
- B) 89 MHz to 108 MHz
- C) 30 kHz to 300 kHz
- D) 3 GHz to 30 GHz

2. **Identify the FM Band**: The FM (Frequency Modulation) radio broadcasting band is typically found in the Very High Frequency (VHF) range of the radio spectrum.

3. **Recall Standard FM Frequency Range**: The standard frequency range for FM radio broadcasting is generally accepted to be from 87.5 MHz to 108.0 MHz.

4. **Analyze Each Option**:
- Option A (5 MHz to 30 MHz) is too low for FM broadcasting.
- Option C (30 kHz to 300 kHz) is in the Medium Frequency (MF) range, not FM.
- Option D (3 GHz to 30 GHz) is in the microwave range, far above FM broadcasting frequencies.
- Option B (89 MHz to 108 MHz) falls within the standard FM broadcasting range.

5. **Select the Correct Answer**: Based on the analysis, the correct answer is **B) 89 MHz to 108 MHz**.

### Final Answer:
