There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 8 weeks. The crashing cost (per week), for the first week (crashing first time), for activity A is: $480, E is $495 and all other activities is: $120 (per week per activity). The crashing cost, second week and onwards (crashing second time), for activity A is $1200 per week, E is $1440 per week and for all other activities is $240 per activity per week. You have a maximum crashing budget of $3005. The maximum possible reduction in the project duration will be: O a. 3 weeks O b. 4 weeks O c. 5 weeks Od. 6 weeks O e. 2 week
