This question is incomplete. However, the completed question is below

A teacher did an experiment to show the movement of particles in solids, liquids, and gases. The experimental set-up is shown below: An inverted glass jar is shown. Small circles representing foam balls are shown inside the jar. A stretched balloon is shown tied at the mouth of the jar. A string is shown drawn out from the middle of the stretched balloon. A hand is shown pulling the drawn out string. The teacher pulled the string attached to the stretched balloon, first slowly, then fast, and finally vigorously. Which of the following is most likely correct about the pulling of the string and the corresponding state of matter being represented? (a) Gas is represented when pulled fast, solid when pulled slowly, liquid when pulled vigorously. (b) Gas is represented when pulled slowly, liquid when pulled fast, solid when pulled vigorously. (c) Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously. (d) Solid is represented when pulled vigorously, liquid when pulled fast, gas when pulled slowly.

The correct answer is C

Explanation:

These question has to do with the "freedom" of particles in each state of matter. In solids, the particles are compact and do not move freely within the solid molecule hence the reason for the definite shape of solid. The particles of liquids move more freely than solid but not as much as gases, hence the reason for there free flowing nature. Particles of gases move more fast and rapidly; colliding against one another and the wall of the container.

From the above description, it can be deduced that to illustrate these particles the teacher will have to represent the particles of the solid as been moved slowly, particles of the liquid will be pulled fast and that of gas will be pulled vigorously using balloons. Thus, the correct option is C
