Correct Answer - Option 4 : Exothermic reaction

The correct answer is Exothermic reaction.

  • An exothermic reaction is a reaction in which energy is released in the form of light/heat.
  • Energy gets transferred to its surroundings in these reactions.

  • Endothermic reaction - In these reactions, they take energies from their surroundings.
  • Replacement reaction- In these reactions, one element is replaced by the other.
  • Redox reaction- Oxidation-Reduction reaction is called Redox reaction or it is also a reaction in which the oxidation number of a participating chemical varies.
