In SI units the power of sound is represented in A. Kgs B. Joules C. Newtons D. Watts

The

correct answer is D. Watts.

The SI unit of power is the watt (W), which is defined as one joule (J) of energy per second (s). Power is the rate at which work is done, or energy is transferred. In the case of sound, power is the rate at which sound energy is produced or transmitted.

The other options are incorrect. Kilogram (kg) is the SI unit of mass. Joule (J) is the SI unit of energy. Newton (N) is the SI unit of force.
