Take into account a graph G and a Breadth First Search $($BFS$)$ tree T originating from root r$.$ Let d$($u$,$v$)$ represent the shortest path length between nodes u and v$.$ If node v is encountered prior to node u during the BFS process, which of the subsequent assertions could be valid?

A$.$ The distance from r to v is greater than the distance from r to u$.$

B$.$ The distance from r to v is equal to the distance from r to u$.$

C$.$ The distance from r to v is less than the distance from r to u$.$
