B and C are clearly the only decent options, but I'm thinking C is better because, in the event the catastrophe does take place, it's better to be much farther away, not to mention that staying away for only a week or so could still get us killed depending on the timing (provided this isn't a hoax.). While we're out on the plains, we can wait and see whether or not our mountain blows its top while simultaneously learning from their people. If it doesn't after a good amount of time, well, we can still come back. It won't even really be lost time, since we'd have learned from their people. If it does go off, that's great, because we've picked the option that launches us furthest away.
Now, what happens if we go with B? Worst case scenario is that we mistime it or aren't far enough off, and so we all die from the volcano. Maybe we time it so that we're some distance downriver, but then what? I don't imagine the river would be much other than toxic sludge with all the junk that the volcano's ejecting, so that's all bad for some time. We don't really have anywhere to go unless the river people we've mostly assimilated bring us back to their ancestral lands or something, at which point we get raped by all of what kicked them out.
Best case scenario, we come back a week and there's nothing much in the way of volcanic catastrophe, we may resume our lives with barely a blip... but we've lost the chance to get the knowledge that these people have, because they've fled to the hills. Granted, we could come up with those things on our own (our people may already be curious about the possibility of riding zebras after seeing these guys, and there may be a chance of native development) but that's slower and also doesn't net us whatever they're smoking.
C just appears to me to be the best option.
