Finer grinding and tricalcium aluminate C3A causes rapid hardening.

While early strength is given to the cement by tricalcium silicate C3S.

Rapid hardening cement has greater strength in early stage as compared to opc. This is due to the extra amount of lime. So C is correct.

In rapid hardening, cement has high percentage of tricalcium silicate and a low percentage of dicalcium silicate.

It is due to the large proportion of lime grinded finer than the normal cement.
