Show answer and solution

Answer: (A) A-III, B-IV, C-II, D-I

(A) The troposphere extends upward to about 10km(6.2milesorabout33,000feet)10km(6.2milesorabout33,000feet) above sea level.
(B) The Electrical-layer or E-part of stratosphere lies approximately 100km100km over Earth’s surface
(C) The F2{F}_{2}-part of thermosphere lies approximately 300km300km over Earth’s surface.
(D) D-part of Stratosphere lies approximate 65−75km65-75km
over Earth’s surface
Thus, A-III, B-IV, C-II, D-I.
