Answer:
Conflict.
Step-by-step explanation:
Conflict is when something happens that leads to a struggle between two or more things. This is a result of mainly diverse or contrasting interests and struggles between conflicting or opposing forces.
In the given excerpt from "To Build a Fire" by Jack London, the protagonist is facing a conflict in his attempt to get to the camp. The conflict results from his need to get to his camp as soon as possible but he had to slow down after he got wet in the lake. This scene presents a conflict of interest, a struggle between two opposing forces - his situation which prevents him from progressing forward to his destination and the cold weather which is detrimental for his life.
Thus, the conflict is between the need to stay alive and get to safety as soon as possible and the cold, snowy environment that he was stuck in.
