hey there!!!
I believe the answer is C). Direction. Since when something in speed changes, it can cause the direction to change or position but I would mainly say if there is a change in spped then the dircetion will somehow or somewhat change also.
Hope that helps!!! :)
An object is accelerating if there is a change in speed and/ or C. Direction.
Acceleration is any change in the speed OR direction of motion.
An object is accelerating if its path is turning or curving, even if its speed is not changing.
