Answer:
I would allude to Elizabeth Bennet's "Pride and Prejudice".
Explanation:
The word "allude" means to make a brief reference to something or someone. In that case I imagine that I would like to write a text where I have alluded to Elizabeth Bennet of "Pride and Prejudice". That's because she represents a strong female character with her own ideas and strong reasoning at a time when women were discouraged from thinking by themselves and exposing their ideas.
This character would fit very well as a reference in a text on the right and respect for women.
