Friends see the options clearly.
Obviously the answer is C3S But in options it is not given (he gives only tricalcium).
C3s increase with lime content.
Answer is D.
Specific surface and burning at high temperature is next to c3s.

Early stage strength of cement is responsible for "finer grinding & higher content of tricalcium " are correct.

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.
