Solution
The correct option is B Exosphere
Troposphere :- The troposphere starts at the Earth's surface and extends 8 to 14.5 km high (5 to 9 miles). Stratosphere :- The stratosphere starts just above the troposphere and extends to 50 km (31 miles) high.
Mesosphere :- The mesosphere starts just above the stratosphere and extends to 85 km (53 miles) high.
Thermosphere :- The thermosphere starts just above the mesosphere and extends to 600 km (372 miles) high.
Ionosphere :- The ionosphere is an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 km (30 miles) above the surface to the edge of space at about 965 km (600 mi), overlapping into the mesosphere and Thermosphere.
Exosphere :- This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 mi).
The correct answer is B .
