Choose the correct group of conventional sources of energy from the following:
- A.Hydro power, geothermal energy, tidal energy
- B.Nuclear energy, solar energy, hydel power
- C.Oil, natural gas, firewood
- D.Coal, firewood, biogas
Correct answer
Explanation
The correct answer is C, oil, natural gas and firewood. Conventional sources are those in long use before modern technology offered alternatives, that is coal, petroleum, natural gas, firewood, cattle dung cake and water power. All three items in this group belong to that list, so the group is wholly conventional, which is what the question asks for.
Option A mixes hydro power, which is conventional, with geothermal and tidal energy, both non conventional. Option B puts nuclear and solar energy, which are non conventional, beside hydel power. Option D is the closest trap, because coal and firewood are conventional, but biogas is counted among the non conventional sources, so the group is not pure. Reading every item of every group before choosing is the only safe method in such questions.
