Name a technique to control the nitrous oxide emissions.

• A. Selective Catalytic Reduction
• B. Electrostatic Precipitation
• C. Activated Carbon Filtration
• D. Condensation

Answer: (A)

Selective Catalytic Reduction uses a catalyst and a reducing agent (like ammonia or urea) injected into the combustion exhaust to convert nitrogen oxides into nitrogen and water. This directly lowers NOx emissions, and since nitrous oxide is part of the NOx family, this method effectively reduces N2O as well. The other options don’t target nitrogen oxides: electrostatic precipitation removes particulates, activated carbon filtration adsorbs gases and vapors on carbon, and condensation removes condensable substances. So, this technique is the best fit for controlling nitrous oxide emissions.
