Answer:
C). To provide comic relief
Step-by-step explanation:
Comic relief is introduced in a literary work that offers humor that provides an emotional break to the readers from the intense and serious mood of the tragic plot. It is literary device that offers light-hearted elements to balance the seriousness by offering comic and funny elements. This excerpt from "Romeo and Juliet" exemplifies the author's purpose to provide comic relief to the audience. In this scene, the nurse invokes humor through her ridiculous outlooks and bawdiness. The 'sword' in this scene is added humorously with a comic element. Thus, the purpose of this dialogue is to provide comic relief to the readers.
