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 retard the initial setting time, therefore we should add in less amount.
So, option A is the correct answer.
