Why not option A?
When concrete 1st placed it quickly sets termed as initial setting after which it dries and increase hardening at a decreased rate.

The concrete gains strength in first 28 days after that it gains strength very slowly.

Answer must be A.
Concrete gets harder after initial setting time and its continuous also after 28 days.

The concrete is assumed to never gain its complete strength. Hence answer D I guess.

Strength of cement increases initially but after cement strength goes on decreasing. Approximately 50 % after 24 months period.

I think answer should be A because I read in many literature heat of hydration in 3 days is occurred about 50%.

Yes, the correct answer should be A.

The correct answer is A because in first 7 days it gains 66% of strength after 28 days it is assumed to gain full strength but after 28 days also there will be an increase in strength gain at the lower rate.
