Answer:
The correct option that lists a vector quantity from the scenario is B. acceleration 8 km/h/s south.
A vector quantity has both magnitude and direction, and acceleration is a vector quantity. In this scenario, the car accelerates uniformly, meaning that its acceleration is constant in magnitude and direction. The acceleration is given as 8 km/h/s south, which means that its magnitude is 8 km/h/s and its direction is south.
The other options are not vector quantities because they either have no direction (distance and speed) or the direction is given as a scalar instead of a vector (velocity). The distance traveled by the car is a scalar quantity and has no direction associated with it. The speed of the car is also a scalar quantity and only gives information about the magnitude of the car's velocity, but not its direction. The velocity of the car is given as 5 km/h north, but it is not a vector quantity because it does not give information about the rate of change of velocity with respect to time (i.e., acceleration).
