Only option A is right.

The difference of rapid-hardening cement to of ordinary Portland cement is the quantity of Limestone (tri-calcium silicate) used as raw material, which gives high early strength to the cement. It attains early strength due to a larger proportion of lime grounded finer than normal cement.

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

All the difference of rapid hardening cement to that of ordinary portland cement is the quantity of lime stone (tri-calcium silicate) used as raw material, which gives the high early strength to the cement.

1st option along with 2nd option gives high strength at an early stage.
In Option D it is given tricalcium only. Not C3S.
Thus Option C is the correct answer.

I think the right answer will be D.

Higher content of tricalcium silicate.

Burning at high temperature and fine grinding gives more strength of cement.

Option D is correct. Because early strength (i.e) the first 7 days strength depends upon tricalcium silicate. But we have the only option to increase the calcium content by increase the lime cement.

The heat of hydration increased by c3s content increased so early strength develop and if fineness of cement increases with an increase in strength.
