Match the following columns and choose the appropriate option :
| Sphere of the Earth | Feature |
|---|---|
| (a) Lithosphere | (i) Plant and Animal Kingdom |
| (b) Hydrosphere | (ii) Made up of rocks and minerals |
| (c) Atmosphere | (iii) Various sources of water |
| (d) Biosphere | (iv) Thin layer of Air |
Answer: B
The correct matching is (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
The Earth has four domains. The lithosphere is the solid crust, made up of rocks and minerals (ii). The hydrosphere is all the water, oceans, rivers, lakes, ice and groundwater, in its various sources (iii). The atmosphere is the thin layer of air surrounding the Earth (iv). The biosphere is the narrow zone where the other three meet and life exists: the plant and animal kingdom (i).
Option A pairs every sphere with the wrong feature, and options C and D shift the pairs round, so only B matches all four.
