As we increase the lime content, the amount of C3S increases. Hence the option C is correct.

Contains more tri-calcium silicate (C3S) and finely ground.

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!

For rapid hardening cement -cement has to grind finer its surface area not less than 3,25000 sqmm. So answer A is correct.
If we increased the lime content the initial setting time also increase.
