Answer 2

The answer to this question will be option D, all of the above.

• A signal is a gesture, action, or sound that is used to convey information or instructions, typically by prearrangement between the parties concerned.
• It is clear from the definition that a signal is a previously agreed movement.
• Signals are also used to direct or command other people or things. For example, Trains are directed using signals.
• A signal is also referred to as the future direction. For example, The clouds signal the oncoming rain.
• Here, the clouds are showing the future direction by predicting rain in a short time.
• Hence, 'signal' can be identified with either of the three sentences.
• So, the answer to this question will be option D, all of the above.
