I find it difficult to imagine herself allowing someone to drag her somewhere and touch her clothes but I'd say B is closest answer.
Again, I'm pretty sure she'd die before allowing someone to tear her clothes off, let alone rape her. She'd feel irritated up until someone touches her.
Neither? I could see her hoping it was good for them too depending on her mood. The story will reveal more of her inner workings as it progresses.
C, if it wasn't her intention to provoke this action.
When I try to quantify Widow's physical prowess I try to imagine what a gymnast who's been retired for two years could do. She's excellent with a knife, has powerful legs with a very strong core, and relies on technique more than power. I wouldn't say Claire is anywhere close to being as strong as Natasha... Outside of the bed, of course.
I feel as if the gist of this post is to gather what Widow would do if someone attempted to rape her and succeeded.
During the act, she would feel disgusted toward herself for allowing it to happen. Situations like that are second-nature to her and it wouldn't be as traumatic to her as it would for the average person.
Afterward, assuming they survived through having sex with her, I doubt she'd rest until she found each one of them and made them regret it.
I hope you found the answer you were looking for
