I thought it was B.

Well, the police car is pretty linear unless is turns it
A rotating becon is like the unit circle rotation.
The angle of the building has noithing harmonic about it unless it is a really strange building.
And a bouncing ball will slowly bounce lower and lower and lower....

And all that means you are right.
