• D. all

Answer 1

The correct option is B ultrasonic waves stir up the dust/dirt particles.

Ultrasonic waves are used for cleaning hard to reach places such as spiral tube, odd shaped machine parts etc. The object to be cleared is kept in the cleaning solution and the solution is subjected to the ultrasonic waves. The ultrasonic waves stir up the dust/dirt particles. These particles get detached and the object is thoroughly cleaned.
