Question

Match the pollutant in Column-I with its source in Column-II and choose the correct option.
Column-I Column-II
(i) High levels of Sulphur dioxide (a) Natural pollutant
(ii) Endosulfan (b) Agricultural practices
(iii) Pollen (c) Automobile exhaust
(iv) Gaseous and particulate lead (d) Electric power plants

• A. (i)–(d), (ii)–(a), (iii)–(b), (iv)–(c)
• B. (i)–(d), (ii)–(b), (iii)–(a), (iv)–(c)
• C. (i)–(d), (ii)–(c), (iii)–(a), (iv)–(b)
• D. (i)–(d), (ii)–(b), (iii)–(c), (iv)–(a)

Hint:

Remember: Power plants → SO\textsubscript{2}, Agriculture → Pesticides, Automobiles → Lead.

Answer 1

The Correct Option is B

Step 1: Understanding pollutants and their sources.
Different pollutants originate from specific natural or human-made activities. Identifying their correct sources helps in understanding environmental pollution.
Step 2: Correct matching.
High levels of sulphur dioxide are mainly released from electric power plants due to burning of fossil fuels.
Endosulfan is a pesticide widely used in agricultural practices.
Pollen is a naturally occurring pollutant released from plants.
Gaseous and particulate lead mainly originates from automobile exhaust.
Step 3: Verification of option.
Only option (2) correctly matches all pollutants with their respective sources.
Step 4: Conclusion.
Hence, option (2) is the correct answer.
