Question

Fill in the blank with the correct possessive adjective: Ce sont ______________ feutres.

Answer 1

Hi,
Ce sont nos feutres.

Answer 2

Since the noun "feutres" (felt pens) is plural, we need a corresponding possessive adjective, for example,

ce sont nos feutres. (our felt pens)
ce sont vos feutres. (your felt pens)
ce sont leurs feutres. (their felt pens)

Any of the three are grammatically correct, unless more context is presented or assumed.
