Q33,paper2,j14. Consider a system with five processes P0 through P4 and three resource types R1, R2 and R3. Resource type R1 has 10 instances, R2 has 5 instances and R3 has 7 instances. Suppose that at time T0 , the following snapshot of the system has been taken :

Allocation,                                R1,                                          R2,                                          R3

P0	0	1	0
P1	2	0	0
P2	3	0	2
P3	2	1	1
P4	0	2	2

Max

R1	R2	R3
7	5	3
3	2	2
9	0	2
2	2	2
4	3	3

Available

R1,R2,R3

 3, 3, 2 .

Assume that now the process P1,requests one additional instance of type R1

and two instances of resource type R3.. The state resulting after this allocation will be

(A) Ready state (B) Safe state

(C) Blocked state (D) Unsafe state

Answer B.
