Explanation:
The correct sequence is (A) Morse code – A. M. Radio – F.M. Radio – World Space Radio. This sequence reflects the historical development of communication technologies:

  • Morse code was the earliest form of communication, used to transmit text messages over long distances using coded signals.
  • A. M. (Amplitude Modulation) Radio followed, allowing audio signals to be transmitted via radio waves.
  • F.M. (Frequency Modulation) Radio came next, offering improved sound quality over A. M. Radio.
  • World Space Radio represents the modern satellite radio technology, which uses satellites to transmit signals globally.

This progression shows the evolution of communication technology from simple coding systems to advanced satellite radio.
