Pick up the correct statement from the following:

[A]. High percentage of C3S and low percentage of C2S cause rapid hardening
[B]. High percentage of C3S and low percentage of C2S make the cement less resistive to chemical attack
[C]. Low percentage of C3S and high percentage of C2S contribute to slow hardening
[D]. Low percentage of C3S and high percentage of C2S provide greater resistance to chemical attack
[E]. All the above.

C3S = initial strength of concrete in 28 days.
C2S= final strength of concrete that is the ultimate strength.
C3A = initial setting time of concrete.
C4AF= a final setting time of concrete.
