Locking is good strategy for synchronization. However, it may lead to problems such as deadlocks. One way to avoid deadlock is to schedule threads carefully. Assume the following characteristics of threads T1, T2, and T3: T1 acquires and releases locks in a fixed order of L1, L2 T2 acquires and releases locks in a fixed order of L1, L3 T3 acquires and releases locks in a fixed order of L3, L1, and L2 For which schedules below is deadlock possible? A: Possible, B: Not Possible Schedule T1 runs to completion, then T2 and T3 run concurrently T1 and T2 run concurrently to completion, then T3 runs T1, T2, and T3 run concurrently T1 runs to completion, then T2 to completion, then T3 runs T1 and T3 run concurrently to completion, then T2 runs Your Answer
