A. "God pardon sin! wast thou with Rosaline?"
B. "Hence from Verona art Thou banished; / Be patient, for the world is broad and wide."
C. "Ah, Juliet, I already know thy grief, / It strains me past the compass of my wits: / I hear thou must, and nothing may prorogue it, / On Thursday next be married to this county."
D. "Take thou this vial, being then in bed, / And this distilled liquor drink thou off."

C. "Ah, Juliet, I already know thy grief, / It strains me past the compass of my wits: / I hear thou must, and nothing may prorogue it, / On Thursday next be married to this county."

This quote shows Friar Lawrence trying to come up with a plan to help Juliet avoid marrying Paris, which ultimately leads to the plot escalating towards its tragic conclusion.
