Why Does Something Weigh Less on the Moon Than on Earth

Why does something weigh less on the Moon than on Earth?

A) The farther something is from Earth, the lower its weight.
B) The Moon's lower mass creates a lower force of gravity at its surface.
C) The object's weight is the same on the Moon as it is on Earth.
D) Earth's gravity pulls in the opposite direction as the Moon's, so the net force is reduced.
E) The Moon has no atmosphere to apply a downward force on surface objects.
