Answer:
The correct adjective to describe Mohammed in this sentence is "casablancais." Here's a breakdown of the sentence: "Mohammed est de Casablanca." - "Mohammed" is the subject of the sentence, referring to a person named Mohammed. - "est" is the verb, meaning "is" in English. - "de" is a preposition meaning "from" in English. "Casablanca" is a proper noun, referring to the city of Casablanca. To describe where Mohammed is from, we need to use the adjective form of Casablanca. In French, adjectives must agree with the gender and number of the noun they modify. Since "Casablanca" is a singular, masculine noun, the adjective form we use is "casablancais." So, the correct adjective to describe Mohammed in this sentence is "casablancais." It indicates that Mohammed is from Casablanca.
