(d)

Work done by retarding force = change in kinetic energy

Since, retarding force  and kinetic energy of both bodies are same so, stopping distance will be same. Hence, (a) is correct.

Or

It means more is the mass, less is the initial speed

Or

Hence, more is the mass, less is the time of stopping. Hence, (b) is correct

It means more is the mass, more is the momentum

Hence, (c) is correct.
