Answer 1

Answer:

(d) Burning of fuel emitting heat

Step-by-step explanation:

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. It is an exothermic chemical process in which there is evolution of heat. Thus the correct answer is option (d).
