To determine the latest time activity A can be finished and not delay any activity, we need to use the backward pass method. We start at the end of the project and work our way back to the beginning. The latest time an activity can be finished is the latest start time of the activities that depend on it.

Activity J has a finish time of 0, which means all activities must be finished by week 0. Therefore, we start with activity J and assign a finish time of 0 to it.

Next, we look at all activities that directly precede J, which are G and H. We know that J must finish by week 0, so the latest G and H can finish is also week 0. This means we assign a finish time of 0 to both G and H.

Moving further back, we look at activity F. It directly precedes G and H, so we take the largest of their finish times, which is 0, and subtract the duration of activity F (3 weeks) to get a finish time of week 3 for F.

We repeat this process for activities D, E, and I, working our way back to activity A. When we get to activity A, we take the largest finish time of the activities that depend on it (D and E) which is week 8, and subtract the duration of activity A (4 weeks) to get a finish time of week 4 for A.

Therefore, the latest time activity A can be finished without delaying any activity is week 4, and the best choice is C.
