Answer:
The correct answer is option B, that is, products.
Step-by-step explanation:
A reaction in which the heat gets captivated by the system is termed as the endothermic reaction. The reactants captivate heat to get transformed into products. Therefore, there is greater heat content in products. On the other hand, the reaction in which the heat is discharged by the system is termed as the exothermic reaction. The reactants discharge heat to get transformed into products. Therefore, there is lesser heat content in the products.
Thus, for the given question, the correct answer is products.
