Consider a system with seven processes $A$ through $G$ and six resources $R$ through $W$.
Resource ownership is as follows :
process $A$ holds $R$ and wants $T$
process $B$ holds nothing but wants $T$
process $C$ holds nothing but wants $S$
process $D$ holds $U$and wants $S$ & $T$
process $E$ holds $T$ and wants $V$
process $F$ holds $W$ and wants $S$
process $G$ holds $V$ and wants $U$
Is the system deadlocked ? If yes, _______ processes are deadlocked.
- No
- Yes, $A, B, C$
- Yes, $D, E, G$
- Yes, $A, B, F$
