Answer 1

Answer: (D)

Both A and B

Green muffler or green belt vegetation is rows of trees and shrubs grown and maintained to serve as noise absorbers. It also reduces air pollution because the trees and shrubs absorb pollution gases and cause settling of suspended particulate matter. Green muffler or green belt vegetation is specially planted along roads and rails for absorption of noise, pollutant gases and dust generated by moving vehicles.

So, the correct answer is 'Both A and B'.
