Detailed Solution

The above statement is true.
If we drop two objects of different masses from a certain height, we know that the two objects must reach the ground simultaneously. But we don't see that here because the air offers resistance to the objects falling through it. Air resistance is a friction force cancelled out by the object's weight during the free fall. That's why the heavier object reaches the ground first than the lighter object.
If two objects of different masses fall from a certain height in a vacuum, then both objects will reach the ground simultaneously because there will not be any air resistance in the absence of air.
