(a) 10 km height over earth's surface
(b) 70 km height over earth's surface
(c) 180 km height over earth's surface
(d) 270 km height over earth's surface List - II
(i) Thermosphere
(ii) Mesosphere
(iii) Stratosphere
(iv) Troposphere

• A. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
• B. (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
• C. (a)-(iv), (b)-(ii), (c)-(i), (d)-(i) [Note: Correcting option logic]
• D. (a)-(iv), (b)-(ii), (i) and (i) belong to higher regions.

Hint:

Mnemonic: **T**rust **S**mart **M**en **T**he **E**most (Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere).

Answer 1

The Correct Option is A

Step 1: **Troposphere**: 0 to 12 km (Matches 10 km).
Step 2: **Stratosphere**: 12 to 50 km.
Step 3: **Mesosphere**: 50 to 80 km (Matches 70 km).
Step 4: **Thermosphere**: Above 80 km (Matches 180 km and 270 km).
