AMatch box, fire wood and kerosene
BOxygen, fuel and heat together
COxygen, a match box and fire wood
DMatch box, fire wood and oxygen
Answer & Solution
Correct answer: B. Oxygen, fuel and heat together
1. Fire needs three things present together, often called the fire triangle.
2. Those are oxygen to support burning, fuel to burn, and heat to start and sustain it.
3. Remove any one of the three and the fire goes out, which is the principle behind every extinguisher.
4. Fire wood is a type of fuel, so naming both is naming one component twice while leaving heat missing.
5. A match box is only a means of supplying heat, not a component of the fire itself.
