Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Pick the odd one out from the following. Hint - Controlling air pollution.

• A. Silencers
• B. Scrubbers
• C. Fabric filters
• D. Electrostatic precipitators

Answer 1

The correct option is A Silencers

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Silencers control noise pollution while others control air pollution. To control the particulate matter in air, we need to deploy smoke stacks with electrostatic precipitators. Fabric filters, scrubbers, and inertial separators should be fitted to factories. Noise pollution can be curbed by fitting silencers to generators.
