Question

Oil paper experimented was conducted in the following areas. Which of the following area will produce minimum pollutants on the paper?

• A. Industrial sector
• B. Agricultural sector
• C. An area equipped with catalytic precipitator
• D. None of the above

Answer 1

The correct option is C An area equipped with catalytic precipitator

The oil-paper test is the test to detect the presence of hydrocarbons. The contaminants and the pollutants which are composed of the hydrocarbons present in the soil, water, and air can be detected. If the industries use the catalytic precipitators, there is the reduction in the release of the harmful gases in the atmosphere. This reduces the pollutions and the presence of the contaminants in the area.

Thus, the correct answer is option C.
