Final answer:
Danforth tells Proctor that Elizabeth is pregnant in Act 3 of The Crucible.
Step-by-step explanation:
In Act 3 of The Crucible, Danforth tells Proctor that Elizabeth Proctor is pregnant. This information is revealed during the trial when Proctor is asked to confirm whether his wife is pregnant. However, when asked directly, Elizabeth denies being pregnant to protect her husband's reputation. It is later revealed that Proctor had told Danforth about the pregnancy privately, which Danforth uses as evidence to question Elizabeth's credibility. This revelation adds tension to the trial and impacts the outcome of the story.
