A wouldn't work. Eva has shown to be vulnerable to flirting before, but that's because Justin was flirting with her. Cody's flirting skills aren't that great I'd still fall for him though.

B is a possibility, since Eva could see Cody's helplessness and decide to show some mercy. She's not a merciless monster, after all. She just has anger issues.

C would not work because...really...

D would make Eva impatient and not really make any progress toward convincing her that she should let Cody live.

So all that being said, I'm going with Option B.
