Match List I with List II
A. Troposphere       I. Approximate 65-75 km over Earth's surface
B. E-Part of Stratosphere      II. Approximate 300 km over Earth's surface
C. F$$_2$$-Part of Thermosphere    III. Approximate 10 km over Earth's surface
D. D-Part of Stratosphere     IV. Approximate 100 km over Earth's surface
Choose the correct answer from the options given below :

The different atmospheric layers are located at characteristic heights above the Earth’s surface.

• Troposphere extends from Earth’s surface up to about $$10\text{-}12km.$$
  Therefore:

A→$$III$$

• E-region of ionosphere lies approximately around 100 km height and is part of the lower ionosphere associated with the stratosphere/mesosphere region.

$$B\rightarrow IV$$

• $$F_2​-$$layer is the upper ionospheric layer present in the thermosphere around 300 km above Earth.

$$C\rightarrow II$$

• D-region lies at the lowest ionospheric level around $$65\text{-}75km.$$

$$D\rightarrow I$$
