- Amicrowaves
- Bvisible light
- Cultrasonic waves
- Dinfrared radiation
Explanation
SONAR (Sound Navigation and Ranging) detects underwater objects by emitting ultrasonic (high-frequency sound) waves and analysing their echoes. Microwaves, visible light and infrared radiation attenuate rapidly in water and are not used. Hence option C is correct.
