Find the shortest route from node $1$ to node $7$ in this network. $1$ to $2$ is $71$ to $3$ is $91$ to $4$ is $182$ to $3$ is $32$ to $5$ is $53$ to $2$ is $33$ to $5$ is $44$ to $6$ is $35$ to $2$ is $55$ to $3$ is $45$ to $6$ is $66$ to $5$ is $26$ to $7$ is $3$

Let X$\_$ij be the decision variables. X$\_$ij $=1$ if the arc from node i to node j is on the shortest route, otherwise X$\_$ij$=0.$ After formulating this problem and solving it using LINDO$/$LINGO$,$ which of the following arcs is on the shortest route from node $1$ to node $7?$ Pick all that applies.
