Answer
B. Any of these
Explanation
A fire is a process/chain reaction which requires three essentials elements to ignite and continue to burn: Heat, Fuel, and Oxygen – this is often referred to as the fire triangle. Interrupting any of these conditions can extinguish a fire.1 - Heat: Fire needs heat to start, maintain and its propagation goes from the heat source directly to the fire material.2 - Fuel: Material that is being burned in the fire. Without materials or compounds to consume fire can't start or continue.3 - Oxygen: All fires need oxygen to exist. This is due to the reactive nature of oxygen. When enough heat and fuel are present, fire forms due to the exothermic reactions that occur. With an absence of oxygen, the chain reaction pauses hence the abolition of fire.By implication, the correct answer would be that to stop the chain reaction and extinguish a fire, you could deprive it of any of these required components. Whether it is heat, oxygen, or fuel specifically would depend on the context but removing any of these would interfere with the chain reaction key to a fire.
