• A. They do not produce noise during the operation
• B. They do not produce chemical reactions in the solutions
• C. They are easy to produce
• D. They can produce perfectly homogeneous solutions

Answer 1

The correct option is D They can produce perfectly homogeneous solutions

Ultrasound having a frequency different from a frequency of a standing wave generated from the ultrasound vibrators symmetrically arranged on the walls at the both sides of the channel to stir and mix the sample fluids.
