A)Total time is 13 days, total cost is $1,500.
B)Total time is 12 days, total cost is $2,000.
C)Total time is 12 days, total cost is $2,300.
D)Total time is 11 days, total cost is $1,850.
E)Total time is 11 days, total cost is $2,350.

To determine the best choice for crashing the project, we need to look for the activity with the lowest crashing cost per day (the cost to reduce the activity duration by one day). Based on the information given in the table, this activity is G, with a crashing cost of $350 per day. Since we need to reduce the total time of the project by one day, we should crash activity G. This will reduce the total duration of the project from 12 days to 11 days, and the total cost from $2,200 to $1,850. Therefore, the best choice is D.
