QUESTION :-

Choose the correct statement [NCERT Exemplar Problems]

(a) Sun can be taken as an inexhaustible source of energy

(b) There is infinite storage of fossil fuel inside the earth

(c) Hydro and wind energy plants are non-polluting

(d) Waste from a nuclear power plant can be easily disposed off

ANSWER :-

(a) Sun can be taken as an inexhaustible source of energy

EXPLANATION :-

Technically, the sun is not a source of inexhaustible energy, since every star eventually burns out (they die after the stage of Red super-giant). However, the sun's internal fuel supply will keep it burning for at least 5 to 6 billion years, enough to be considered inexhaustible for all practical purposes.
