Which word from this excerpt best convey its tone

C. Desolation, solitary.

Explanation:

In these lines, Crusoe reflects on his luck. He tells us that humans often complain about their lives, but he thinks that we only do so because we do not know how bad the alternative could be. He states that he often complained about his life being less than satisfactory, and now that he actually lives on an island in complete solitude, as he often thought about before, he realizes his life was in fact quite good. The tone is one of regret and sadness, and this is highlighted by his use of words such as "desolation" and "solitary."
