athe limits of habitable zone above the surface of the Earth
bregions inside the Earth where shale gas is available

AnswerUPSC’s answer is (c).
The Goldilocks Zone is the habitable zone around a star, where a planet is neither too hot nor too cold and liquid water can exist on its surface. Astronomers use the term while searching for Earth-like planets beyond the solar system. It does not refer to the Earth's atmosphere, shale gas deposits or meteorites.
Why each option is right or wrong
- (a) The term concerns the zone around a star, not a layer above the Earth's surface.
- (b) Shale gas regions have no link with the term.
- (c) Correct: it refers to the search for Earth-like planets in space.
- (d) Meteorites with precious metals are unrelated.
