A)14
B)12
C)11
D)13
E)None of the above

The PERT expected activity time is calculated using the formula: (optimistic time + 4 x most likely time + pessimistic time)/6. Plugging in the given values, we get: (4 + (4 x 14) + 18)/6 = 72/6 = 12. However, it is important to note that this is only an estimate and the actual time could vary. Therefore, the closest choice to the calculated value is D (13).
