How does Tranio convince the merchant to be Vincentio?

• A. Since the man is from Mantua, Tranio claims that his life is in danger because the prime ministers are fighting and Mantuan travelers who reach Padua will be killed, so Tranio promises him protection
• B. He offers him a position in the household
• C. He promises him money for the role
• D. He asks him to keep the arrangement a secret until Bianca's wedding

Answer: (D)

Disguise and manipulation rely on keeping the ruse hidden until the right moment. Tranio, posing as Vincentio, needs the Mantuan merchant to buy into the arrangement without exposing the deception. By asking him to keep the plan secret until Bianca’s wedding, Tranio protects the scheme from early scrutiny and chance interruptions, allowing Lucentio’s pursuit of Bianca to proceed under the cover of Vincentio’s authority. The secrecy is what makes the deception workable long enough for the marriage plan to unfold. The other ideas miss the crucial move: the scheme depends on confidentiality, not on offering status, money, or a promise of danger, to secure the merchant’s cooperation.
