Choose the correct network diagram for this project.Part 3 A. StartFinishA6B1C3D3E4F6G5 Edit coordinates (0,0) In the diagram, there are 2 rectangles. The one on the left is labeled Start, and the one on the right is labeled Finish. There are 7 circles labeled inside the circle using the letters from A to G. There is a number below the letter inside each circle. There are arrows that indicate the flows through the circles from Start to Finish as follows: Rectangle Start has an arrow that connects to circle A 6, circle A 6 connects to circle B 1, circle B 1 connects to circle C 3 and to circle D 3, circle C 3 also connects to circle D 3, circle D 3 connects to circle E 4, circle E 4 connects to circle F 6 and to circle G 5, and circles F 6 and G 5 both connect to rectangle Finish.
