Ravenous Bugblatter Beast of Traal
I can't envision even wanting to play with anyone who's answer isn't A. If you're going to play a game that involves things like the combat and therefore the possibility of death, but you can't have it happen you YOU, that's not cool. If the party wants to split, or say one/few members have a lengthy conversation apart from the rest of the group and you can't handle it, I don't want you derailing the rest of our fun.
That said, a DM who separates out a PC for an extended period without talking to the player or providing ways to get him back in can also be a jerk. If you're captured and the DM expects you to do nothing for most of the session that's not fun. But that doesn't mean immunity to being captured.
If your character dies, and other players decided they want to finish out the dungeon first (several session) before going to get your character raised, you and the DM shoudl work out something. That's no fun at all.
tl;dr: everyone should be on the lookout for each other's fun, both for extended lengths of sitting out but also not whining if some consequences come your way.
