Solution

The correct option is A Chalk in water
Solution allows the beam of light to pass through it. Since vinegar, lemonade and salt water are solutions, they will allow the beam of light to pass through them. However, chalk in water is not a solution, therefore, it will not allow the beam of light to pass through it.

Q. Which of the following substances does not allow electricity to pass through?

Three mixtures A, B and C are obtained by stirring three different solids in water taken in separate beakers. When mixture A is allowed to stand for some time, its particles settle at the bottom of the beaker. When a beam of light is passed through mixture A in a dark room, the path of light becomes visible when observed from the side of the beaker. When mixture B is allowed to stand for a considerable time, its particles do not settle down. Mixture B, however, scatters the beam of light just like mixture A. The particles of mixture C do not settle down on keeping and it also does not scatter a beam of light passing through it
