Ai-c, ii-a, iii-d, iv-b ✓ Correct

Bi-a, ii-b, iii-c, iv-d

Ci-b, ii-a, iii-d, iv-c

Di-c, ii-d, iii-a, iv-b

Correct answer: (A) i-c, ii-a, iii-d, iv-b

Explanation

A toxic pollutant like benzene poisons organisms even at low concentrations in water.

Chlorine here is placed as a non toxic pollutant type in this classification.

Macroscopic pollutants are large visible items such as food cans and other debris.

Pathogenic pollutants are disease causing organisms like protozoa in the water.

The match sorts pollutants by toxicity, size and their ability to cause disease.

Protozoa in water can spread illnesses such as amoebic dysentery.
