Answer:
I had to do a little Googling because I had no idea what "The Wife of Bath's Tale" even is lol. And I got a few answers.
"The theme of power is evident throughout the tale."
"Sex, marriage, and domination."
"Women and femininity."
So considering out of all the options you've provided and the options I found, Feminism might be the most accurate answer.
Good luck, hope this helped!
