B)The Early Start Time is 4
C)The slack for this activity is 2
D)The duration of this activity is 2
E)The activity is on the critical path

The slack is calculated by subtracting the Early Finish time from the Late Finish time or by subtracting the Early Start time from the Late Start time. Therefore, the slack for this activity is 2 (10-8). The Early Start time is the Early Finish time minus duration, which is not given. Similarly, the Late Start time is the Late Finish time minus duration, which is also not given. Therefore, choices A and B cannot be correct. The duration of the activity is also not given, so choice D cannot be correct. The activity is not on the critical path because it has slack. Therefore, choice E cannot be correct.
