Answer 1

Answer: (A), (B), (D)

It is an eco-friendly fuel compared to conventional fuels.

Natural gas is a flammable gas which consists largely of methane (90%) and other hydrocarbons, occurring naturally underground and is used as a fuel. It produces very less pollution compared to the conventional fuels like petrol, diesel, coal, wood etc. as it doesn't produce ash (unburnt carbon).
