Based on the given information, the estimated expected time for project completion is the sum of the optimistic time, four times the most likely time and the pessimistic time divided by six.

(expected time) = (optimistic time + 4 x most likely time + pessimistic time) / 6

= (25 + 4 x 120 + 225) / 6

= 121.67 days (rounded to 120 days)

Therefore, the best choice is D, 120 days.
