the answer should be D since velocity is displacement over time, B is definitely wrong.

So the answer sheet is wrong? Can elaborate? :)

so it cannot be B because when velocity is constant, displacement should increase at a constant rate instead of decreasing

actaully D is also weird because when velocity increases non-uniformly the displacement should also increase non-uniformly.
