The scientists from which US University have found that cold plasma can kill 99.9% of airborne viruses?

[A]. Clemson University
[B]. University of Michigan
[C]. Stanford University
[D]. Yale University

Answer: Option B

Explanation:

Scientists from University of Michigan in the United States have found that dangerous airborne viruses can be rendered harmless on-the-fly when exposed to 'cold plasma' - a stream of energetic, charged fragments of air molecules. The researchers have measured the virus-killing speed and effectiveness of non thermal plasmas - the ionised, or charged, particles that form around electrical discharges such as sparks. A non thermal plasma reactor was able to inactivate or remove from the air stream 99.9% of a test virus. The researchers hope to one day harness this capability to replace the surgical mask.
