Solution

The correct option is B False
Endothermic reactions are those in which heat is being taken up from the surroundings to complete the reaction.
Exothermic reactions are those that give up heat to the surroundings.
The reaction between quick lime and water is as follows:
CaO + H₂O → Ca(OH)₂↓
Here quick lime is added to the water, heat is formed along with the insoluble calcium hydroxide(slaked lime). As heat is generated in this reaction it is called an exothermic reaction.
Hence, the given statement is false.
