Free slack is the amount of time an activity can be delayed without delaying the subsequent activities or the project completion date. To calculate free slack, we need to find the lowest value of total slack for all the activities entering into a specific activity. This is because the activity with the lowest total slack is the one that is most critical to the project schedule. Once we have identified this activity, we subtract its total slack value from the total slack values of all other activities that also enter into the same activity. This gives us the free slack for that activity. So, choice C is correct as it subtracts the lowest value of total slack for the critical activity from the total slack values of all other activities that also enter into the same activity.
