Time increase i.e retarder gypsum.
The right answer is A.
The right answer is A.

A is right. I agree.

No, @Ssuman.
Because gypsum is a retarder so it prolongs the setting time and calcium chloride is an accelerator and it shortens the setting time.

Gypsum is 200% correct answer it increases the setting time because it is a retarder. And calcium chloride decreases the setting time so that conc can be sets early as it is an accelerator.

Which material is used for decreasing the setting time of cement?

I agree retarder increase setting time to delay takes place. Where as in accelerator decrease setting time to react fastly.

Gypsum increase setting time of cement.

Gypsum is a retarder means it is delaying the setting time implies that required the setting time is more that means increasing the setting time. After all, gypsum is the right answer.

Gypsum used as retarder it's slow down the reaction rate so initial setting time will increase.

Is this adding sugar, increasing concrete setting time?
