Answer:
D. Presence of oxygen
Step-by-step explanation:
If the amount of oxygen increases, the intensity of the fire will increase as well because oxygen supports the chemical processes that occur during the fire. Wind increases the supply of oxygen, which is why Lolo Delfin's ancestral home will burn down faster in the presence of wind.
The presence of a fire extinguisher and the use of water would stop the fire, which is why options A and B are incorrect.
