As the vessel containing water is moving with a constant speed, thus no pseudo force acts on the water in the vessel frame. Also the vessel frame is an inertial frame for water. Hence the moving liquid (water) forms the surface as same as that when the liquid was at rest.
Hence option $A$ is correct.
