In Act 3 of "The Crucible," when John Proctor brings a list of 91 names that attest to the innocence of those accused of witchcraft, the judge, Deputy Governor Danforth, essentially responds by saying he doesn't believe the claims made by the signers. He is skeptical of the motivations behind the list, leading to the situation where those who signed it are put in a difficult position. So, the correct answer is:
A. Says he doesn't believe them.
Danforth's skepticism highlights the themes of authority and the consequences of mass hysteria present throughout the play.
