Answer 1

Hint
Nonrenewable Resources of energy are that energy resources which will deplete over a lifetime. They are consumed at a rate faster than they can naturally reproduce, many of these resources take millions of years to replenish. Examples of undefined are coal, oil, and materials used for nuclear energy. And we have to use such resources which can be generated easily and cause less pollution.

Complete step by step solution
We learned in our Life that energy is one of the basic requirements to run life. However, it is not only living things which need energy to move and carry out daily activities. The machines and appliances in our world around us also need some form of energy to do work.
Energy sources have energy that is stored within them and can be used to make something happen, for example, energy stored in petrol can be used to make a car go.
Renewable sources are ones which can be recycled or reused. Non-renewable sources cannot be reused and so there is a limited amount available and when that runs out there will be none left.
Various sources of renewable energy
-Solar energy
-CNG
-Bio energy
-Hydro energy
-Bio-thermal energy
Various sources of non-renewable energy
-Petrol and Diesel
-Coal
-Crude oil
-Minerals
-Nuclear energy
We prefer renewable sources over non-renewable sources of energy. So best suit fuel is CNG for vehicles.
Option (A) is correct answer.

Note
However, most of the world's energy sources are derived from conventional sources-fossil fuels such as coal, oil, and natural gases. These fuels are often termed non-renewable energy sources. Although the available quantity of these fuels are extremely large, they are nevertheless finite and so will in principle 'run out' at some time in the future.
