• A. $47$ to $230kHz$
• B. $47$ to $230MHz$
• C. $470$ to $960MHz$
• D. $88$ to $108MHz$

Answer 1

The correct option is D

$88$ to $108MHz$

Explanation for Correct Option:

Option (D):

1. Throughout the world, the FM broadcast band falls within the VHF or the Very-High Frequency part of the radio spectrum.
2. Usually, a range of $87.5$ to $108.0MHz$is used for FM radio broadcasting.
3. FM stands for Frequency Modulation.
4. In this technique, the frequency of an information or message signal is modulated with respect to a carrier wave with a much higher frequency.
5. The high energy of the carrier wave helps to transmit the modulated signal to a faraway distance.
6. In this method, the message signal is not easily lost to noise.

Hence, the correct answer is option (D).
