Graph-theoretical treatment of deadlocks: Select all of the following statements that are true. A knot is a strongly connected subgraph of a directed graph. A process p is unblocked in a resource allocation graph if there is no request edge starting at p. In an expedient system, the resource allocation graph will never contain any satisfiable request edges. The banker's algorithm is defined for consumable resources. A knot is a necessary condition for a deadlock.

Question
Graph-theoretical treatment of deadlocks: Select all of the following statements that
are true.
A knot is a strongly connected subgraph of a directed graph.
A process p is unblocked in a resource allocation graph if there is no request
edge starting at p.
In an expedient system, the resource allocation graph will never contain any
satisfiable request edges.
The banker's algorithm is defined for consumable resources.
A knot is a necessary condition for a deadlock.
In order to show that a system state is safe, the Maximum Claim Graph must be
completely reducible.
