Answer 1

Hint: Wood is burnt to light up the fire and the food can be cooked in this fire keeping in a beaker. Similarly, the coal can be used as a fuel in a stove or an oven and given the energy for cooking. The food needs to be in a completely separate environment from fire.

Complete Solution :
- We all know that there are some substances that provide us with energy in any form of heat or light. All such substances are known as fuels. Our vehicles work on petrol or diesel. Petrol or diesel is a fuel. Similarly, we know wood is burnt to provide heat to cook food. The wood is also fuel.
- So, the assertion says that the Coal is one of the fuels used to cook food. This statement is true because the coal is used to light up the fire for cooking.
- The coal like the wood can be used to fire a stove or an oven and the food can be cooked in this fire but only if the food is in a completely separate environment from the fire like in any container. So, the reason is also true.
- And the reason is the correct explanation of the assertion.
Thus, the correct answer is that both Assertion and Reason are correct and Reason is the correct explanation for Assertion
So, the correct answer is “Option A”.

Note: It must be noted that Coal is a form of carbon which is combustible. It is formed from the remains of the dead plants. When the dead plants decay into peat for over years, these are converted into coal by heat and pressure of deep burial.
