From Table 2.2, we can see that the earliest expected time of completion (EF) for the project is 34 weeks. If we increase the expected times for activities A, G, and H by 2, 3, and 4 weeks, respectively, the new EF can be calculated as follows:
EF(A,B,C,D) = 5 + 7 + 5 + 2 = 19
EF(E,F) = 19 + 3 + 3 = 25
EF(G,H) = 25 + 12 + 7 = 44
EF(I,J,K) = 44 + 8 + 6 + 5 = 63
EF(L) = 63 + 3 = 66
Therefore, the project's new earliest expected time of completion is 66 weeks, which is an increase of 32 weeks from the original EF of 34 weeks. Thus, the answer is C, as the increase is greater than 4 weeks but fewer than or equal to 6 weeks.
