The correct response is:
by contrasting the reactions of Elizabeth and Mr. Collins
The use of third-person omniscient narration allows the author to present the differing perspectives and attitudes of Elizabeth and Mr. Collins regarding marriage. Elizabeth's refusal to accept Mr. Collins’ proposal highlights her desire for genuine affection and compatibility in marriage, while Mr. Collins’ insistence that her rejection is merely a formality reflects his naive view of courtship and social expectations. This contrast underscores Austen’s critique of the societal norms surrounding marriage, showcasing the importance of mutual respect and personal happiness over financial considerations or social pressure.
