Quick Setting Cement as the name indicates, these types of cements are used where quick setting is needed. The quick setting cement is manufactured by adding a small percentage of aluminum sulphate and then it is finely grinded with cement.
And also for quick setting action a small percentage of gypsum or retarder is added. The aluminum sulphate is mainly added to accelerate the setting time fast.

For normal cement gypsum add 2% which causes increasing setting time.

The answer will be option A. Because gypsum is such a chemical compound which is liable for the setting of cement.

I think the option will be both A and C.

Gypsum is an retarder not accelerater.

The Correct answer is A Because gypsum is such a chemical compound which is liable for the setting of cement.

Answer is A and C because gypsum is retarded setting time and aluminum sulphate is produced quick setting but best answer is C.

I think it is both A and C.

Option C is CORRECT.
Because quick setting cement mainly produced by adding a small amount of ALSO4 and fine grinding other than RHS OR OPC. And reduced CASO4 (GYPSUM).

C is the appropriate answer. I agree with the given answer.

C -, cz gypsum is retardar, which mean increase setting time,
But here asked about the quick setting, i.e accelerator, mean decrease setting time which is aluminium sapphire (Al2So4).
I think answer A & C both are correct because gypsum is mainly increase setting time but here it said less amount of gypsum and aluminium sulphate is accelerate setting so both answer A & C is correct.

I think A is the right answer. Or one can add calcium chloride as an accelerator.

Gypsum is retarder. It delays the setting time.

It is for rapid hardening cement. But for quick setting cement, it is option C.
