Answer:
A) True. The droplets will move in parabolic arcs.
Explanation:
When the dog shakes the drops that leave the fur they leave with a speed and an angle; These are now subject to the out of gravity that accelerates them in the vertical axis and has no outside the horizontal axis, so they must describe a parabolic movement.
Pair to describe a central force that changes its speed, but this force does not exist once they leave the dog
Let's check the answers
A) True. You agree with the analysis
B) False. There is an outside on the axis and therefore the line is deviating
C) False. There is no radial force that creates this movement
