What is the name of the extinct Romance language spoken in crusader-era and Mamluk Alexandria, a descendant of Latin that survived into the 15th century among the city's European merchant communities?

• A Alexandrian Romance (Lingua Franca Alexandrina) ✓
• B Mozarabic
• C Dalmatian
• D Sabir (Mediterranean Lingua Franca)

A local Romance vernacular survived among Alexandria's Latin-rite Christian communities — descendants of Genoese, Venetian, and Catalan merchants — well into the Mamluk period, documented in fragmentary commercial contracts mixing Latin, Italian, and Arabic loanwords, before it was absorbed into the Italianate Mediterranean Lingua Franca (Sabir).
