The Answer is right because it is asking the for the early setting time of cement which is due to tricalcium aluminate but for the early strength of cement, tricalcium silicate and ultimate strength or final strength is due to dicalcium silicate. So don't be confused be clear.

C3S for initial setting.
C3A for the flash setting.
C2s for Ultimate strength.
C3A for the flash setting.
C2s for Ultimate strength.

Give ans is right.
Here asked about initial setting, not asked speeds the setting. Kindly read the que again.

Hello guys, the answer is right, because C2S is responsible for early STRENGTH of cement in the INITIAL stage, in this question ask the initial setting time of cement.

C3S - early strength.
C2S - ultimate strength.
C3A - the initial setting of cement.
Heat of hydration C3A > C3S > C4AF > C2S.
C2S - ultimate strength.
C3A - the initial setting of cement.
Heat of hydration C3A > C3S > C4AF > C2S.
