Question

Match List-I with List-II:

• B. (A)-(I), (B)-(III), (C)-(IV), (D)-(II)
• C. (A)-(I), (B)-(II), (C)-(IV), (D)-(III)
• D. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Hint:

Understand pollution sources and their characteristics for accurate matching in environmental science.

Answer 1

The Correct Option is A

Point sources are discrete and identifiable. Non-point pollution comes from widespread activities like agriculture. Groundwater is affected by industrial spills, and surface water includes runoff, sewage, etc.

Answer 2

Definitional matching: Point-source pollution originates from a single, identifiable outlet, such as a pipe or discharge point, that can be directly monitored and regulated.
Non-point-source pollution instead arises from diffuse, widespread activity over a large area, such as fertiliser and pesticide runoff from farmland, with no single traceable outlet.
Groundwater contamination is commonly linked to localised, high-intensity events like industrial spills or leaking storage that seep downward, while surface-water contamination collects widespread inputs such as overland runoff, sewage discharge, and erosion sediments.
Aligning each pollution category with its defining source characteristic, discrete and traceable versus diffuse and widespread, and localised seepage versus collected runoff, reproduces the same correspondence as the first option.
