Two objects of different masses falling freely near the surface of the Moon would

ahave different accelerations
bundergo a change in their inertia
chave same velocity at any instant✓ Correct
dexperience forces of same magnitude

Explanation

In free fall, the acceleration g is independent of mass. The relation for velocity is v = u + gt, so velocity depends not only on initial velocity (u) and time (t). Hence, if two objects are released together from the same point (neglecting air resistance) under identical initial conditions (e.g., u = 0), then at any instant their velocities will be the same.
