Answer: C) Weight
Step-by-step explanation:
The car still retains its mass because the matter is still there. The particles that make up the car are still present. The car also has inertia since inertia is effectively a measure of mass. We can rule out choices A and B because of these reasons.
The car wouldn't have weight in space because the pull of gravity isn't as strong. The pull of gravity is still there, but it's much more miniscule which produces the weightlessness of the object. Recall that the force of gravity reduces as the distance between the objects increases.
