Solution

Exothermic reaction
Exothermic reactions are reactions in which heat energy is released in the form of light or heat.
Endothermic reaction
Endothermic reactions are reactions in which heat energy is absorbed.
Dilution of sulphuric acid
Sulphuric acid $(H_{2} {SO}_{4})$ is one of the strongest acids.
On dilution of sulphuric acid, it evolves huge amount of heat.
Hence, the dilution of sulphuric acid is an exothermic reaction.
