Answer:
A. Proctor is arrested.
Step-by-step explanation:
In Act III of The Crucible, the girls are arrested and brought forward to Governor Danforth to present their testimonies. During the proceedings, Proctor tries to defend his wife from Abigail's accusations. He explains to Danforth that his wife is not a witch according to Abigail's testimony, but that Abigail made that up because she wanted to have an affair with him.
He presented evidence to the court to convince them that he was telling the truth but Abigail and the other girls continued putting up the pretense. When Elizabeth Proctor was summoned to the court and asked if her husband was coerced into an affair with Abigail, she denied that. Mary succumbed to pressure when she admitted that she was a witch and this led to the arrest of Proctor who argued that Abigail and the other girls were lying.
