Consider the following table of activities that describes a project network. After all the crashing you can do is done (assuming you can crash only one activity at a time), how many paths are critical? Which activities remain noncritical? Would you characterize this network as sensitive or insensitive?
A) Two critical paths, only C is noncritical, insensitive
B) Three critical paths, only E is noncritical, sensitive
C) Four critical paths, only D is noncritical, sensitive
D) Three critical paths, only C is noncritical, sensitive
E) Two critical paths, only E is noncritical, insensitive
