A
Hemisphere, Lithosphere, Troposphere, and Ionosphere
B
Exosphere, Stratosphere, Mesosphere, and Ozonosphere
C
Hydrosphere, Atmosphere, Biosphere, and Geosphere
D
Thermosphere, Atmosphere, Hemisphere, and Ionosphere
Explanation: 

Detailed explanation-1: -Everything in Earth’s system is placed into one of the four subsystems: land, water, living things, or air. The subsystems are known as “spheres.” Specifically, they are known as the geosphere (land), hydrosphere (water), biosphere (living things) and atmosphere (air).

Detailed explanation-2: -Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air).

Detailed explanation-3: -The five systems of Earth (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) interact to produce the environments we are familiar with.

Detailed explanation-4: -Biosphere is all organisms on Earth, for example, plants, animals, and microorganisms, which are tiny, living things such as bacteria; and is the only sphere considered biotic. Geosphere is all of the solid lands in Earth’s crust and is considered abiotic.

Detailed explanation-5: -The hydrosphere is the sum of Earth’s water, in the ocean, the ground, on the surface, and in the air.
