D Correct answer
Explanation

One is not able to cut the stream of running water as particles of water have forces of attraction between them. Water (liquid) particles do not have very large spaces between them. Therefore, the force of attraction between the particles is high. Moreover, particles of every kind of matter are small and they are continuously moving.
