Question

Match List I with List I:

List I		List II
A	AM Broadcast	I	88-108 MHz
B	FM Broadcast	II	540-1600 kHz
C	Television	III	3.7-4.2 GHz
D	Satellite Communication	IV	54 MHz​-890 MHz

 
Choose the correct answer from the options given below:

• A. A-II, B-III, C-I, D-IV
• B. A-II, B-I, C-IV, D-III
• C. A-IV, B-III, C-I, D-II
• D. A-I, B-III, C-II, D-IV

Answer 1

The Correct Option is B

To solve this question, we need to match each type of communication or broadcast service in List I with its corresponding frequency range in List II.

1. AM Broadcast:

   Amplitude Modulation (AM) broadcasts typically operate in the Medium Frequency (MF) band. The usual range for AM radio broadcasting is 540{-}1600 \ \text{kHz}. Therefore, AM Broadcast corresponds to II.

2. FM Broadcast:

   Frequency Modulation (FM) broadcasts, which provide better sound quality, typically operate in the Very High Frequency (VHF) band. The range for FM radio broadcasting is 88{-}108 \ \text{MHz}. Thus, FM Broadcast matches with I.

3. Television:

   Television broadcasting operates in the VHF and Ultra High Frequency (UHF) bands. In many regions, this includes frequencies like 54{-}890 \ \text{MHz}. Thus, Television matches with IV.

4. Satellite Communication:

   Satellite communication utilizes higher frequencies, specifically in the C-band and Ku-band. One common segment is the 3.7{-}4.2 \ \text{GHz} range. Therefore, Satellite Communication corresponds to III.

Combining these matches, the correct answer based on the given options is: A-II, B-I, C-IV, D-III.
