Answer: To show that it is a metaphor and not literal
Explanation:
''Talk the hind legs of a donkey'' is having a meaning ''making a donkey sit down on its rear end'' which is not something that donkeys do naturally. It is used when we are describing a person who is talking to much. This phrase has its origins in Ireland.
In this case, the author is considering that person can talk much about her tales.
Can we see the paragraph?
Yup B is the answer because you can eliminate all the other answers because the paragraph doesn’t do A, C, or D
