Answer :
Answer:
Imperfect duty.
Explanation:
Imperfect duty is a rational obligation that a person must do in times of need. These duties are duties that do not occur all the time. They rarely occur only in times of need. The nature of rational existence and fragility of humans are reflected in imperfect duties.
Sometimes humans become helpless and they take as well as render help from others. This is because humans cannot do everything alone. As a child, someone has to feed us. As a sick patient, someone has to take care of us. Thus, imperfect duties come into play during these times. They are duties that humans do for others as a rational duty.
Here, the neighbor who entered the burning house was frightened but he chose to act heroically because of rational obligation which naturally forced him to aid others.
