The law of suggests that the orbit of planets is not circular but.

Newton's law of universal gravitation ... massaged and manipulated
with a lot of calculus and geometry ... predicts that closed gravitational
orbits are ellipses.  

The circle is such a precise special kind of ellipse that a circular orbit
never occurs.  The chance of it is like the chance of flipping a coin and
having it land standing up on its edge ... possible, but very improbable.

Pretty sure the answer is b : )

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
