I think answer is B because A gives rapid hardening more heat.

I think B is the correct answer because in good quality cement 32% of Di-calcium silicate, 4% of Tricalcium silicate, 10. 5% of Tri-calcium aluminate & 9% of Tetra calcium alumino ferrite.

No, it's correct.
The typical compound compositions of this type are:
55% (C3S), 19% (C2S), 10% (C3A), 7% (C4AF), 2.8% MgO, 2.9% (SO3), 1.0% ignition loss, and 1.0% free CaO.

According to my view, B is correct because Di-calcium silicate provide ultimate strength.

I think, option B is correct.

B is the answer. Because ultimate strength is provided by Dicalcium silicate.

Given answer is correct. I agree.

Tricalcium silicate is the right answer.
Because it gives the early strength if there is no early strength in concrete structure then what is the profit?
No one wt for 2-3 years for gaining complete strength by di calcium silicate. So right answer is option A.

Answer should be B because free lime in the C2S is less as compare to C3S.

The answer is B because early strength is much needed for any structure.
