The activity on critical path in network diagram because the non-critical path activity do not have impact on the duration s long as the critical path remains same.

 so is it H

Activity C is the answer

 If both are on critical path then how to decide

 If both are on critical path then Activity that comes FIRST should be the one one to shorten

Could someone explain the answer in bit detail, as this seesm to be intresting question, also refer material for studies for similar kind of situations

If both are on critical path then Activity that comes FIRST should be the one to shorten
