What is le rez-de-chaussée?
Sholpan [36]

Answer:

b

Explanation:

In American English, "ground floor" and "first floor" are generally synonymous and thus can both be used for rez-de-chaussée. So when you’re in a French elevator, instead of seeing a button marked "G" for "ground floor," you’ll see one marked "RC" for rez-de-chaussée.
