Which of the following commonly causes hepatitis?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Water Pollution
Option (1) Air Pollution — Incorrect. It causes diseases of the respiratory, nervous and circulatory systems, not hepatitis.
Option (2) Noise Pollution — Incorrect. It harms people through loud sound and cannot carry an infection.
Option (3) Land Pollution — Incorrect. Garbage and chemical residues spoil the soil; hepatitis spreads through contaminated water.
Option (4) Water Pollution — Correct. When people drink or use contaminated water, the germs in it enter the body, so polluted water becomes a source of water-borne diseases. The diseases commonly caused by contaminated water are diarrhoea, intestinal worms and hepatitis.
