Which of the following quotes spoken by Friar Lawrence shows the strongest example of how he advances the plot over the course of Romeo and Juliet?

A. "God pardon sin! wast thou wit 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."

The strongest example showing how Friar Lawrence advances the plot is D. "Take thou this vial, being then in bed, / And this distilled liquor drink thou off." This quote is significant because it is Friar Lawrence who gives Juliet the potion that will make her appear dead, ultimately setting off a chain of events that leads to the tragic conclusion of the play.
