Which quotation from "to build a fire" best shows that the man is inexperienced in the extreme temperatures of the yukon?

"he was sure to frost his cheeks; he knew that, and experienced a pang of regret that he had not devised a nose strap of the sort bud wore in cold snaps."

"he struck the fingers repeatedly and returned them to the mitten, baring the other hand for the purpose of eating."

"at the very least it meant delay, for he would be forced to stop and build a fire, and under its protection to bare his feet while he dried his socks and moccasins."

"lifeless they were, for he could scarcely make them move together to grip a twig, and they seemed remote from his body and from him."
