The statement that best describes the conflict involving Chillingworth is:
Chillingworth wants revenge against Hester's lover.
In Nathaniel Hawthorne's "The Scarlet Letter," Chillingworth, Hester Prynne's estranged husband, seeks vengeance against the man who had an affair with Hester, which ultimately leads him to torment Reverend Dimmesdale, who is revealed to be Hester's lover.
