The reaction of water with slaked lime is studied by ..........

The correct option is A Putting a lot of water into slaked lime

The reaction of slaked lime with water is an exothermic reaction which releases a high amount of heat.

To study the chemical reaction occurring between slaked lime and water, slaked lime must be taken in beaker and a lots of water must be poured on it.

When we add slaked lime to water, it doesn't get dissolved properly.

Sprinkling of little water on slaked lime also doesn't give proper result as slaked lime requires huge amount of water to dissolve.

Hence,option B is correct answer.
