(B)- Cheap
(C)- Burn easily in air

Answer 1

Hint: Fuel is a substance that provides energy in the form of heat generally, which is used to perform many works. Good fuel will come under the category of that fuel which is consumed by the people majorly.

Complete step by step answer:
Good fuel will have the following properties in it:
-It is available in nature easily and present in abundance, so that people will readily get good fuel for their use.
-It is available at an appreciable price in the market or we can say that it is present in the cheap price in the shops, so that any person who also belongs from the lower class family will not face any problem to purchase the good fuel.
-Good fuels have high calorific value i.e. they produce high amounts of heat or energy on burning. And with high calorific value they also have low ignition temperature, so that anyone can burn the fuel without any special circumstances.
-Along with the above mentioned points, good fuels after burning leave ash behind.
So, according to the mention qualities of good fuel answer of the above question should be all of these i.e. Good fuel is readily available, cheap & burns easily in air.

Hence, option (D) is correct.

Note: Here some of you may think that how much fuel will come under the category of good fuel if it is present at a cheap price, so here don’t think that the quality of this fuel is not good if it is available at a cheap price.
