Heat is released in an exothermic change.

The correct option is A True

Exothermic change: Those reactions which are accompanied by the evolution of heat are known as exothermic reactions.

• Heat is given out during the change.
• The heat liberated is indicated by a positive sign on the product side.
• An exothermic reaction is represented as $\mathrm{Reactants}\to \mathrm{product}+\mathrm{Heat}$
• Rusting iron, settling, chemical bonds, explosions, and nuclear fission are a few examples.

Thus, the given statement is True. I.e., Heat is released in an exothermic change.
