Answer:
Les filles font une promenade à la campagne.
Explanation:
The original answer choices were:
A.) au
B.) aux
C.) à le
D.) à la
"Au" is normally paired with masculine words; e.g., "Je vais au cinéma." "Aux" applies to all words; e.g., "Je vais aux magasins. "À le" is masculine, and it is the same as "au." It is not correct because when "le" or "les" comes after "à," they must be contracted. This does not apply for the feminine preposition, "à la." As we can see in the sentence, "les filles" means "the girls," so the missing preposition must pair with feminine words. So that leaves us with Option D.
Hope this helps :)
