D.

Answer ( Option A)

7.05 cm

Solution

For compressive strength test at least 3 specimen cubes of size 70.6 mm are prepared.
Compressive strength is taken as an average of the results of the three cubes
Note: Large size specimen (i.e. 150 mm) cubes can not be made since cement shrinks and cracks develop.
