To explain why "B: Fuel" is the correct answer:
- Fuel:
- Fuels are substances that can undergo combustion to release heat and light.
- During combustion, chemical energy stored in the fuel is converted into heat and light energy.
- This process is essential for generating energy in various forms, like in engines, stoves, or power plants.
- Examples of fuels include wood, coal, oil, gas, and gasoline.
Therefore, fuel is the substance that gives heat and light after combustion.

Explanation:
Fuel:
- Fuel is a substance that can be consumed to produce heat or energy through a chemical process called combustion.
- When a fuel undergoes combustion, it reacts with oxygen in the air to produce heat and light.
- This process releases energy in the form of heat and light, which is why fuels are used in various applications such as heating, cooking, and generating electricity.
Flame:
- A flame is the visible, gaseous part of a fire that emits light and heat.
- The flame is produced when a fuel undergoes combustion and reacts with oxygen to form products such as carbon dioxide and water vapor.
- The heat and light emitted by a flame are a result of the energy released during the combustion process.
Combustion:
- Combustion is a chemical reaction between a fuel and oxygen that produces heat and light.
- During combustion, the fuel is oxidized, releasing energy in the form of heat and light.
- This process is essential for a fire to sustain itself and continue producing heat and light.
Therefore, the substance that gives heat and light after combustion is fuel. The fuel undergoes combustion, producing a flame that emits heat and light as a result of the chemical reaction with oxygen in the air.
