D Correct answer
Explanation

Air pollution is due to various substances that holds the potential to hinder the atmosphere or the well  being of the living beings surviving in it. The sustainment of all things living is due to a combination of gases  that collectively form the atmosphere; the imbalance caused by the increase or decrease of the percentage  of these gases can be harmful for survival. All the above mentioned a, b & c points are the cause of air  pollution.

So, the correct answer is 'All of the above'.

  2. Using pesticides in farms

  3. Developing housing estates

  4. Quarrying for limestone
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The use of excessive chemical fertilizers and pesticides results in the water pollution and soil pollution. The construction of the housing estates results in air pollution. The quarrying of the limestone also results in the release of the particles causing air pollution. The increase in the forest reserves does not result in any kind of pollution. 

Thus, the correct answer is option A.

Lead (Pb) causes

  1. Soil pollution

  2. Air pollution

  3. Radioactive pollution

  4. All the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Lead is an important pollutant of soil and atmosphere. Lead is a heavy metal and very immobile element. Hence, the lead may quickly reach very high concentrations locally. Lead is a prominent pollutant released from factories manufacturing dry cells and batteries. In the atmosphere, lead is released by combustion of fossil fuels. Fossil fuels contain lead compounds as an additive as antiknock agents. Combustion of such fuel in vehicles leads to air pollution.
