Final answer:
Option (D), Elizabeth advises Mr. Bennet to stop Lydia from going to Brighton due to fear of trouble; her father dismisses her concerns.
Step-by-step explanation:
The student is inquiring about a specific plot detail from Jane Austen's 'Pride and Prejudice'. Elizabeth, also known as Lizzy, advises her father to prevent Lydia from going to Brighton because she fears Lydia will get into trouble due to her immature and imprudent nature.
Mr. Bennet, convinced that Lydia will be safe under the colonel's care, dismisses Elizabeth's concerns, failing to see the potential risks associated with Lydia's behaviour and the trip. This particular event foreshadows later complications in the novel.
