In time-cost optimization of a project, crashing is done.
On all the activities
On all the activities lying on the critical path
Only on activities lying on the original critical path and having flatter cost slopes
On original critical activities and those that become critical at any stage of crashing in the order of ascending cost slope
Correct Answer :
