Tricalcium Silicate (C3S) hardens rapidly and is largely responsible for initial set and early strength. In general, the early strength of Portland cement concrete is higher with increased percentages of C3S. Dicalcium Silicate (C2S) hardens slowly and contributes largely to strength increases at ages beyond 7 days.

C3A is the right answer.

Option B is Correct.

C3S - Early strength.
C2S - Strength lateral.
C3A - Setting time.
