Answer 1

Answer: (A), (D)

The correct options are
A Coal and petroleum are fossil fuels.
D Fossil fuels are present in limited quantity.

- Fossil fuel are formed from the dead remains of plants and animals buried for a long time. Coal and petroleum are fossil fuels as they are formed due to the carbonisation of dead plants and animals.
- Fossil fuels are conventional sources of energy. They are non-renewable in nature.
- Petrol is obtained by fractional distillation of crude oil. Petrochemicals are organic chemicals obtained from crude oil and natural gas.
- Fossil fuel reservoirs are not found everywhere and cannot be renewed easily. Hence, they are limited.
