Hello, SLF,
You made just about the tiniest mistake possible in your diagram, which is good news of a sort.
It's not that courageous people
never derive pleasure from facing dangers, it's that courage is not determined
solely by the fact of someone facing dangers because he derives pleasure from doing so.
Basically, if someone struggles through fear inspired by danger and still perseveres in his goal, then that person is courageous,
even if that person also derived pleasure from facing those dangers.
If I have to wrestle a grizzly bear to stop it from attacking someone, and I'm terrified but I do it anyway, that counts as courageous, even if I'm secretly a grizzly-bear-wrestling aficionado who just gets a huge kick out of wrestling grizzlies. At least according to the stimulus.
So for this reason C is immediately disqualified, and D becomes highlighted as the best answer. The fear of danger is a necessary condition of being courageous, so without that fear, there is no courage. The fact of benefit to others is irrelevant, a red herring.
Hope that helps,
Lucas Moreau
