Question
Which of the following is NOT the method for handling deadlock?
The correct answer is
Deletion
This option is not a standard, recognized method specifically named "Deletion" in the context of overall deadlock handling strategies like Prevention, Avoidance, Detection, or Recovery. While deleting a process or resources might be a step taken as part of a Recovery strategy, "Deletion" itself is not classified as a primary method for handling deadlock.

- $P = \{P_1, P_2, P_3, P_4\}$ consists of all active processes in an operating system.
$R = \{R_1, R_2, R_3, R_4\}$ consists of single instances of distinct types of resources in the system.
The resource allocation graph has the following assignment and claim edges.
Assignment edges: $R_1 \rightarrow P_1, R_2 \rightarrow P_2, R_3 \rightarrow P_3, R_4 \rightarrow P_4$ (the assignment edge $R_1 \rightarrow P_1$ means resource $R_1$ is assigned to process $P_1$, and so on for others)
Claim edges: $P_1 \rightarrow R_2, P_2 \rightarrow R_3, P_3 \rightarrow R_1, P_2 \rightarrow R_4, P_4 \rightarrow R_2$ (the claim edge $P_1 \rightarrow R_2$ means process $P_1$ is waiting for resource $R_2$, and so on for others)
