Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.

Statement I:Atmospheric stability determines the ability of pollutants to disperse vertically in the atmosphere.

Statement II:In the summer season in India, the atmosphere is generally stable.

ABoth Statement I and Statement II are true

BBoth Statement I and Statement II are false

CStatement I is true but Statement II is false ✓ Correct

DStatement I is false but Statement II is true

Correct answer: (C) Statement I is true but Statement II is false

Explanation

Atmospheric stability governs how freely pollutants can rise and disperse vertically in the air.

Statement 1 stating this control by stability is accurate.

Strong summer heating warms the surface and makes the lower atmosphere unstable and well mixed.

Statement 2 calling the summer atmosphere generally stable is therefore wrong.

Stable, poorly mixing conditions are far more typical of calm winter nights in India.

Temperature inversions trap pollutants near the ground and worsen air quality.
