In the short story "To Build a Fire" what is the answer to this question?

In the first few sentences, we are in exposition. The following observations are things we may or may not learn in the opening few sentences. Which of these is an accurate description of an observation that foreshadows the coming disaster?

The day is dark and gray.
The sun has not been seen for days.
The man is reluctant to admit his personal limitations, even to himself.
The man's dog is only following him because he is a provider of warmth.

It is definitely not D. Originally I had thought it was C, but I'm not sure.

C seems to be the best answer here. It's the only one that hints at actions that will come during the story.
Thank you!
