Which of the following plays is a story about separated twins?

The play that tells the story of separated twins is Menaechmi, written by the Roman playwright Plautus. This comedic work centers around two twin brothers, Menaechmus of Syracuse and Menaechmus of Epidamnum, who were separated at a young age. The humor of the play arises from the mistaken identities and misunderstandings that occur when the twins inadvertently come into contact with one another without initially realizing they are siblings. This narrative device showcases themes of confusion, the significance of familial bonds, and the comedic potential of identity crises.

The other plays listed do not involve a central theme of separated twins. Captivi focuses on themes of captivity and moral dilemmas, while Epidicus revolves around clever schemes and manipulation for the sake of love. Aulularia, also by Plautus, centers on a miser and the comedic complications surrounding his obsession with wealth. These thematic focuses differentiate them from Menaechmi, making it a unique exploration of the dynamics of twin relationships.
