Answer 1

The correct option is C Use of organic fuels such as fire wood which is cheaper besides being environmentally friendly.

Industrial pollution can be greatly reduced by:

• Use of cleaner fuels such as liquefied natural gas (LNG) in power plants, fertilizer plants etc. which is cheaper in addition to being environmentally friendly.

• Employing environment-friendly industrial processes so that the emission of pollutants and hazardous waste is minimized.

• Installing devices which reduce the release of pollutants. Devices like filters, electrostatic precipitators, inertial collectors, scrubbers, gravel bed filters or dry scrubbers.
• 
  

Apart from the use of above-mentioned devices, other control measures are:

• Increasing the height of chimneys.

• Closing industries which pollute the environment.

• Shifting of polluting industries away from cities and heavily populated areas.
