I believe the Apollo 15 astronauts (Dave Scott?) proved that a hammer and a falcon's feather dropped at the same rate on the airless moon.
So for objects dropped by a six foot tall astronaut, anyhow, D would be the best answer.

D. Are independent of the masses of the objects.
The idea was first introduced by Galileo Galilei, and he experimented dropping some objects from the Tower of Pisa.

d
they hit at the same time
You may find the film on this. One one trip to the moon they made a short movie with a feather and a big rock. They fell at the same rate.

D, in a vacuum all objects accelerate at the same rate.
