both options "C" and "D" are correct in my opinion cause as the car is moving at a constant speed there is no acceleration and as the car is being ridden on a straight road direction of movement also does not change, Hence proving that both option "C" and "D" are correct. I hope my answer was helpful. A very Happy New Year to all
