For the same system, which was assumed to be in a safe state, and using the Banker's algorithm, select the action (decision) that the operating system takes when a request from process P4 is issued, such that R=(1, 4, 2, 0)? Available A B C D 1 5 2 O Po Pi P2 P3 P4 Allocation A B C D 0 0 1 2 1 0 0 0 1 3 5 4 0 6 3 2 0 0 1 4 Max A B C D 0 0 1 2 1 7 50 2 3 5 6 0 6 5 2 0 6 5 6 The system runs the Banker's algorithm and terminates (kills) process P4. The system runs the Banker's algorithm and then asks P4 to wait for some time. The system runs the Banker's algorithm and grants the requested resources to P4. The system runs the Banker's algorithm and grants the requested resources to P4. The system detects a deadlock later on
