1. A-III, B-II, C-I, D-IV
2. A-I, B-II, C-IV, D-III
3. A-I, B-IV, C-III, D-II
4. A-III, B-IV, C-II, D-I

Correct answer: A-III, B-IV, C-II, D-I

Solution

The correct option matches the layers of the atmosphere with their respective altitudes: the Troposphere is approximately 10 km (A-III), the E-part of the Stratosphere is around 100 km (B-IV), the F2-part of the Thermosphere is about 300 km (C-II), and the D-part of the Stratosphere is approximately 65-75 km (D-I). This alignment accurately reflects the known altitudinal ranges of these atmospheric layers.
