Answer:
I believe it would be
Las.
Explanation:
If Los is wrong, (then it probably feminine) meaning it's Las for plural.
The answer is A. "El maletero."
El maletero means the trunk, which is where you can safely store things in a car. The other choices include different parts of a car, but none of which are suitable for storage.
Las puertas - the doors
Los asientos - the seats
Los espejos laterales - side mirrors
Las luces delanteras - front lights
Miraron
