Well for me it’s C because no human really knows when a specific volcano will erupt. Hope this helps!!
The answer would be B, here's why,
Jim’s narrative of his heroic acts is valuable because he records them modestly, giving us an insider view of heroism that is not very glamorous. Jim is not arrogant, but instead is humbled by his mistakes and successes. He takes full responsibility for his errors rather than finding excuses for them, and he confesses to moments of panic, indecision, and regret rather than bragging exclusively of his successes.
I believe the correct answer is pleasant and attentive.
The author is stating in the excerpt that he though he would be getting his freedom back because of his 'gentleness and good behavior.' He wanted everyone around him to feel happy but also to do good things in order to be free again.
