Consider a project with four activities: A, B, C and D. Assume A can be started as soon as the project is kicked off. B can start as soon as A is completed. C and D can start as soon as B is completed. (C and D can happen simultaneously). Normal Duration (in days): A = 4, B = 5, C = 6 and D = 7. The deadline is 13 days from the start; every day of delay beyond this deadline will cost the company $225 (per day). The duration of each activity can be reduced by one day by incurring the following crashing costs: A = 200 $/day, B = 300 $/day, C = 50 $/day and D = 100 $/day. No activitys duration can be reduced by more than one day. What should the project manager do according to the greedy method?

		Crash A, B, C and D by one day each.
		Crash A, C, and D by one day each.
		Crash A and D by one day each.
		Crash A and C by one day each.
