For the network below, the objective is to find the length of the shortest path from node $$P$$ to node $$G.$$ Let $${d_{ij}}$$ be the length of directed are from node $$i$$ to node $$j$$. Let $${s_j}$$ be the length of the shortest path from $$P$$ to node $$j.$$ Which of the following equations can be used to find $${s_G}$$?
A
$${s_G} = Min\,\,\left\{ {{s_Q},\,\,{s_R}} \right\}$$
B
$${s_G} = Min\,\,\left\{ {{s_Q} - {d_{QG}},\,\,{s_R} - {d_{RG}}} \right\}$$
C
$${s_G} = Min\,\,\left\{ {{s_Q} + {d_{QG}},\,\,{s_R} + {d_{RG}}} \right\}$$
D
$${s_G} = Min\,\,\left\{ {{d_{QG}},\,\,{d_{RG}}} \right\}$$
