RPF Constable 2018 Question Paper PDF (16-Feb-2019) (Shift 2)
The correct answer is

Coal

Coal is correct.

Non-conventional sources of energy are renewable sources that are replenished by nature, such as solar, wind, tidal, geothermal and biomass energy. Their large-scale use is relatively recent.

Coal is a fossil fuel formed from plant remains buried over millions of years. It is exhaustible and has been used on a large scale for a long time, so it is a conventional source of energy, along with petroleum and natural gas.

Solar, wind and tidal energy are therefore non-conventional, while coal is not.
