Answer is D.


An object only reach terminal velocity when the weight is equal to the air resistance.


Air resistance increases as velocity increases.


The difference between a light object and heavy object is that heavy object will reach higher terminal velocity as more heavy object has more weight. Therefore, heavy objects will fall faster in air than light objects.
