Answer: A
Explanation: C and D can automatically be ruled out. The Salem Witch trials occurred in the 1600s. I am willing to bet a lot of money that waitresses weren't a common thing, especially so for commoners (we know she's a commoner because rich weren't generally accused of being a witch.) There is no way she would have been near a waitress in her time.
I hope this helps. Have an amazing rest of your week :)
