Abigail is her accuser
d. Abigail
Step-by-step explanation:
Mary Warren states that Elizabeth was accused but she defends Elizabeth and later the court dismisses the accusation. Elizabeth informs Proctor that Abigail wanted to get rid of her and she also believes that Abigail will accuse her of witchcraft and then have her executed.
Elizabeth later gets convinced that it was Abigail who accused her of witchcraft and her motive was to take her place in John's bed.
Hale then visits the Proctors because he wanted to openly speak with everyone whose name has been mentioned in connection with witchcraft.
