Answer 1

Hint: It is planting trees to reduce pollution.

Complete answer:
The green muffler is a technique of reducing the noise pollution by planting trees and shrubs in several rows around the highly populated or noisy places like along roadsides, industrial areas, societies near highways, etc.
The planting of dense trees around these types of areas will reduce noise pollution by filtering out the noise and will prohibit it from reaching the ears of the peoples living in that area.
Additional information
- A muffler in British English is a device used for decreasing the amount of noise emitted by the exhaust of an engine.
- The green muffler is also known as green belt vegetation where trees and shrubs are grown and maintained to serve as noise absorbers.
- It reduces noise pollution along with air pollution as the trees and shrubs absorb polluted gases and settle suspended particulate matter.
- The green muffler is usually planted alongside roads, industries, or railway stations to reduce and absorb the noises caused by vehicles.
- Generally, Ashok and Neem plants are planted which are the best absorber of noise.

So, the correct answer is Along roads.

Note: Similar to the green muffler, a green corridor is also formed which is a thin strip of land that provides proper habitat to support wildlife and acts as a route for animals to shift from one place to another. It maintains greenery and reduces pollution.
