Priority scheduling algorithm could result starvation. Starvation is nothing but indefinite blocking.

Hence, correct option is A.

Priority scheduling can result in starvation. Suppose we have 5 processes of low priority, all of which have arrived at time 0 and however, at time 1, high priority processes keep on arriving. So the low priority processes will be postponed indefinitely hence causing starvation.

FCFS, Round Robin scheduling can never result in starvation.

starvation in scheduling algorithm occurs when any process is favoured over other.

since FCFS and RR doesnt favour any process therfore they are starvation free.in priority based scheduling more priority process gets favoured over low priority hence Ans: A

Consider a system having $’m’$ resources of the same type. These resources are shared by $3$ processes $A,B,C;$ which have peak time demands of $3,4,6$ respectively. The minimum value of $’m’$ that ensures that deadlock will never occur is $11$ $12$ $13$ $14$
