Answer 1

The correct option is D A, B, C and D

Fossil fuels are formed from the carbonisation of organic matter. These resources take a very long time to be formed and are not renewable easily. Hence, fossil fuels are present in limited quantities and are exhaustible. Coal, petroleum, natural gas, etc are examples of fossil fuels.

Steel is an alloy of iron and the formation of steel requires carbon (typically in form of coke).
