I believe the answer to be A since basic examples of time prepositions include: at, on, in, before and after. They are used to help indicate when something happened, happens or will happen.
8.la voiture est de Sophie
9. la voiture à Sophie
here the first sentence means the car is of sophie where as the second sentence meant the car is at sophies'.
The French prepositions à means "to," "at," or "in," while de means "of" or "from."
the answer will be D for apex
La voiture de Sophie
