In schedule development, you create a distribution of probable results for each activity and use it to calculate distribution of probable results for the total project. The technique that you are using is ______ .

A．a schedule compression technique that typically includes reducing schedule activity durations and increasing the assignment of resources to schedule activities
B．a schedule compression technique in which phases or activities that normally would be done in sequence are performed in parallel
C．the timely input of data to calculate the critical path
D．equivalent to minimizing float

A．focuses on managing the resources applied to buffer activities
B．alters the required dependencies in the project schedule to optimize resource constraints
C．adds duration buffers that are work schedule activities to maintain focus on the total float of network paths
D．adds duration buffers that are non-work schedule activities to maintain focus on the planned activity durations
