The PERT expected activity time can be computed using the formula:

Optimistic Time + 4 x Most Likely Time + Pessimistic Time 
_____________________________________________________
                           6

Substituting the given values into the formula:

4 + 4 x 6 + 14 
_______________ = 7
       6

Therefore, the expected activity time is 7 days, so the best choice is C.
