Answer:

The correct answer is c) a chemical change, because a gas was produced.

Explanation:

Sometimes when performing scientific experiments in laboratories, chemical changes are obtained in the elements that have been used, a chemical change is an alteration in the structure of a compound, so the element is different than at the beginning of the experiment.

Generally, when there is a chemical change this is usually irreversible; For example, in the case of Nio, he experiments with yeast, water, and sugar, which puts it in a bottle and closes it with a balloon, this mixture of substances has resulted in a chemical change since the element is transformed in gas.
