Ai-a, ii-b, iii-c, iv-d ✓ Correct

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

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

DNone of the above

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

Explanation

The troposphere holds dust particles along with weather and most of the air's mass.

The stratosphere contains the ozone layer that filters ultraviolet rays.

The ionosphere is linked here with meteors and the reflection of radio waves.

The exosphere, the outermost layer, is matched with the aurora.

Swapping ozone into the troposphere or dust into the stratosphere breaks the layered order.

The stratospheric ozone layer absorbs most of the Sun's harmful ultraviolet radiation.
