A) 1200 
B) 1100 
C) 900 
D) 700 
E) None of the above

Quizplus · Accepted Answer

Starting from Node 2, the minimum length of cable necessary to connect all the nodes is 1100, which can be achieved by the following path:
2-4 (distance: 200)
4-5 (distance: 300)
5-1 (distance: 400)
1-3 (distance: 200)
Total distance: 200 + 300 + 400 + 200 = 1100.
