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.

Rapid Hardening Cement (RHC) are also called high early strength cement. The prime difference between the rapid hardening cement and ordinary Portland cement is the lime content. A large proportion of lime is the distinguishing feature of rapid hardening cement.

Can anyone explain, why we have a higher level of strength requirements for PCC compared to OPC at an early age (3 days and 7 days)?

Option A is correct.

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.

The early strength of "cement"~ fine grinding.
The early strength of "RHC"~ increased lime cement.
So, the given answer is correct.
The early strength of "RHC"~ increased lime cement.
So, the given answer is correct.

The rapid rate of developing of strength in RHC is attributed to.
1. Higher fineness of grinding.
2. Higher content of tricalcium (C3S) and lower content of dicalcium (C2S).
So A and D is the right answer!
