Answer: In "The Necklace", the character that stated “You never go out, and this is such a fine opportunity" is Mathilde's husband.
Step-by-step explanation: "The Necklace" is a short story written by Guy de Maupassant and published in 1884. The main character of the story is Madame Mathilde Loisel, who behaves as an aristocrat, even though she belongs to a lower-middle-class family. When her husband invites her to a party organized by Ministry of Education, Mathilde refuses to go. As a result, her husband tells her "You never go out, and this is such a fine opportunity" in order to convince her to attend the party.
