How does the ending reveal Jack Worthing's parentage?

• A. Jack is revealed to be the son of Lady Bracknell's sister, found as a baby in a handbag by Miss Prism and Canon Chasuble.
• B. Jack is Aragorn's long-lost cousin.
• C. Jack is a figment of Cecily's imagination.
• D. Jack is a professional actor playing a role.

Answer: (A)

The ending hinges on a revelation about Jack’s true lineage. He is shown to be the son of Lady Bracknell’s sister, the baby who was found in a handbag in the cloakroom at Victoria Station and then entrusted to Miss Prism and Canon Chasuble. That single detail changes everything: it makes Jack a legitimate member of the Bracknell family, clearing the obstacles to his marriage prospects and tying together the play’s playful deceptions with a tidy aristocratic tie-in. Wilde uses this twist to lampoon how social status and birth can override other concerns, turning Jack’s apparent “unknown” birth into a fortunate, enviable connection for everyone.

The other options don’t fit the text: the story isn’t about fantasy lineage, Cecily’s imagination, or any role-playing by Jack.
