Incorporating a 4-day lag between activities C and B means the finish time for C will now be 27 (23+4). Since activity B has a finish to finish relationship with C, its early finish time is dependent on C's early finish time. Therefore, activity B's early finish time will increase to 31 (27+4). The early start and finish times for activity A remain unaffected by the lag between C and B, so options A and B are incorrect. Option D is also incorrect because the start time for activity D is not impacted by the lag between C and B. Therefore, the correct answer is C.

Activities a and B Have a Finish to Finish Relationship
