What is the name of the extinct Semitic language, closely related to Arabic, once spoken by the peasant population of the Nile Delta before the Arab conquest?

• A None — Delta peasants spoke a late Coptic dialect, not a Semitic language ✓
• B Nabataean
• C Akkadian
• D Amorite

The pre-Arab rural population of the Delta spoke Bohairic Coptic, the northern dialect of the ancient Egyptian language family (an Afro-Asiatic branch distinct from Semitic), not a Semitic language — the misconception arises from the Delta's proximity to the Semitic-speaking Levant, but the two language families are separate branches of Afro-Asiatic.
