Scenario 1
A thug tells you to give them all your money or they'll hurt you.
What could you say in Japanese to show that you'll comply with their request? Would any of these sound natural for such a situation?　
いいよ　(ii yo) - Fine.
いいだろう。　Fine.
大丈夫　(daijoubu) Okay.
はい　　(hai) Yes.
するよ！　(suru yo) I'll do it!


Scenario 2
A co-worker (not your boss) asks you to do something. You don't want to do it, but you give in anyway. What would you say to show that you're not happy about it? Would it really just be a matter of your tone of voice and body language? Would the below sound natural?
いいよ　(ii yo) - Fine.
いいだろう。　Fine.
大丈夫　(daijoubu) Okay.
はい　　(hai) Yes.
するよ！　(suru yo) I'll do it.

Thanks!
