Audio in television signals are

Options

A. frequency modulated
B. amplitude modulated
C. both frequency and amplitude modulated
D. phase modulated

Explanation

### Step-by-Step Solution:

1. **Understanding the Types of Modulation**:
- In communication systems, there are two primary types of modulation used for transmitting audio signals: Amplitude Modulation (AM) and Frequency Modulation (FM).

2. **Defining Frequency Modulation (FM)**:
- Frequency Modulation is a technique where the frequency of the carrier wave is varied in accordance with the amplitude of the audio signal. This allows for better reproduction of the original sound.

3. **Defining Amplitude Modulation (AM)**:
- Amplitude Modulation involves varying the amplitude of the carrier wave in accordance with the audio signal. While AM can be used for audio, it is more commonly used for video signals in television broadcasting.

4. **Comparison of FM and AM for Audio**:
- FM is generally preferred for audio signals because it provides better sound quality and is more resistant to noise and interference. This means that the audio frequencies can be distinguished more easily, leading to a more accurate reproduction of the original sound.

5. **Conclusion**:
- Therefore, in television signals, the audio component is transmitted using Frequency Modulation (FM) due to its superior ability to reproduce sound accurately compared to Amplitude Modulation (AM).

### Final Answer:
Audio in television signals are frequency modulated (FM).
