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)?

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.

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.
