$($Energy saving WSN$)$ For the Wireless Sensor Network given in the figure bellow, the number on each link indicates the consumed energy of propagating a packet over this link and the numbers in parentheses below the nodes indicate the nodes' remaining energy capacity. find the following $($with all required details$)$:

a$)$ Minimum$-$hop route

b$)$ Minimum $-$ energy consumed per packet route

c$)$ Maximum $($average$)-$ energy capacity route
