It is said that 'Ozone is good up high but bad nearby'. In this context which one of the following is INCORRECT?

  1. Ozone in stratosphere protects us from damaging ultraviolet rays & hence good for us

  2. Ozone in ground level worsens bronchitis or asthma & hence bad for us

  3. Ozone in high-altitude creates a favourable air movement leading to easy air travel

  4. Emissions of NOX from industries or motor vehicles creates ozone in the ground level through chemical reactions

C Correct answer
Explanation

'Ozone is good up high but bad nearby' correctly states that stratospheric ozone protects from UV (A), while ground-level ozone from NOx emissions worsens respiratory diseases (B, D). Option C is INCORRECT because high-altitude ozone does NOT create favorable air movement for travel - it absorbs UV, affecting atmospheric circulation but not specifically 'air travel'. This tests which statement doesn't fit the science.
