Solution
The correct option is B The stationary ship has more inertia because it has more mass. Inertia is the natural tendency of an object to resist a change in its state of motion or rest. Inertia and mass are interrelated. The heavier the objects, the larger the inertia.
Since the ship is much heavier than the car, it offers more inertia.
