First we have to draw the network diagram.

Then we can see that activity E depends on activity B and activity F depends on activity C. So the Hammock Activity duration will be (EF – BC) = (5 – 2) = 3.

The early start time of the Hammock Activity will be the early start of the activity B, which is 7.

Therefore, the correct answer is C) 13, 7.
