How many of Plautus' works have survived to this day?

Plautus, a prominent Roman playwright of the 3rd century BCE, is known for his contributions to the development of Roman comedy. His extant works number around 20, which have been preserved and continue to be studied today. These plays are characterized by their clever use of puns, lively characters, and often comedic misunderstandings, reflecting the social dynamics of his time.

The specific number of approximately 20 surviving works includes notable titles such as "Amphitruo," "Miles Gloriosus," and "Aulularia." The survival of these texts is significant not only for their entertainment value but also for their impact on later literary forms, including the works of later playwrights like Shakespeare and Molière, who were influenced by Plautine comedy.

The other numerical choices do not accurately reflect the consensus of scholarly research regarding Plautus’ surviving plays, making the answer of around 20 the most reliable response.
