A 1900-kg car experiences a combined force of air resistance and friction that has the same magnitude whether the car goes up or down a hill at 27 m/s.

there is no correct list among the choices you've provided.

the list might look something like this:

-- piccolo

-- flute

-- baritone singer

-- baritone horn

-- bass singer
