Answer: Option (b) is the correct answer.

Explanation:

A chemical reaction in which heat energy is absorbed by the reactant molecules is known as an endothermic reaction.

Therefore, upon completion of this reaction the container in which reaction is carried out becomes colder.

A chemical reaction in which heat energy is released by the reactant molecules is known as an exothermic reaction.

Therefore, upon completion or during this type of reaction the container in which reaction is carried out becomes hot.

Thus, we can conclude that when the test tube gets colder as the reaction takes place then it means this chemical reaction is endothermic reaction.
