C. The bus is moving at a constant speed.
Reason: each equal block is covered in the same time, so the magnitude of the velocity (speed) is constant. The direction changes when the bus turns from north to east, so the velocity vector is not constant and acceleration is not a constant nonzero value (it's zero on straight stretches and nonzero during the turn).
