Holly - it wasn't what was said. It was how it was said.
She could have simply said she's not doing scenes anymore. Instead she made it seem like a girl spreading her legs on camera is a bad thing.
She's either too stupid to know that would have been offensive or she didn't care that it was offensive to every girl in that room who still DOES spread her legs on a regular basis. And despite what some people might say, Jenna's not stupid, so I vote for choice B.
