Both are correct. Friction is opposite to the direction of motion or, in the case of static friction, an applied force that attempts to cause motion. A spring's force is opposite and proportional to the displacement from an equilibrium position.
If I had to choose one answer for a fill-in-the-blank question, I'd pick 'spring'
Which force acts opposite of the direction of displacement of the object?
I think it would be friction...but could it be spring?
