Standing on the upper deck raises the centre of mass, making the bus less stable.

B

Standing on the upper deck increases the mass of the bus, causing it to slow down.

C

Standing on the upper deck increases the kinetic energy of the bus.

D

Standing on the upper deck lowers the centre of mass of the bus.
