Quick lime is correct as it is capable of slacking with water and the major part is calcium oxide and minor magnesium oxide.

Fat lime contains 95% of calcium oxide. So fat lime is the answer.

Quick lime is obtain from calcination of pure lime.

caco3 -> cao + co2.

Here cao is called quick lime which slacks with water gives fat lime.

cao + H20 -> ca(oH)2 (slacking).

Here ca (oH) 2 is called fate lime or white lime.
