Final answer:
The momentum of the person is greater than the momentum of the bike.
Step-by-step explanation:
Momentum is directly proportional to the object's mass and velocity.
Since the momentum of an object is calculated by multiplying its mass and velocity, and the person has a greater mass (60 kg) compared to the bike (12 kg), the momentum of the person is greater than the momentum of the bike.
Therefore, the correct statement is:
The momentum of the person is greater than the momentum of the bike.
