Solution

The correct option is D $10$
${(Total cost)}_{period (t_{r})} = {(Previous cost)}_{t_{i}} + {(Crashed cost)}_{t_{f} - t_{i}} - {(Indirect cost)}_{t_{f} - t_{i}}$

The smallest raise occurs when the project is crashed from D to E and the difference between crash cost per day and indirect cost per day is minimum here = project cost at E $-$ project cost

$D = 9500 - 9490 = 10$
