azamat

Answer:

A string is placed under a solution and a crystal grows on the string because the solution is supersaturated.

Therefore, the correct answer to the question is option B.

Explanation:

A saturated solution is defined as a solution in which there is no more space for the solute to be added. All the words in the solution is been filled with the solute which is been added before and mixed well to fill up all the pores. Supersaturated solution is defined as a solution which has a greater number of solute than it was being capable of holding.

As it is clear from the name supersaturated which means more than saturation. And when string is placed under this solution there are some crystal which grows on the strings because of the solute saturation which is being attached to the string.
