A multithreaded program P executes with x number of threads used y number of locks for ensuring mutual exclusion while operating on shared memory locations. All locks in the program are non-re-entrant. i.e. if a thread holds a lock l, then it cannot re-acquire lock l without releasing it. If a thread is unable to acquire a lock, it blocks until the lock becomes available. The minimum value of x and the minimum value of y together for which execution of p can result in a deadlock are:

1.	A multithreaded program P executes with x number of threads used y number of locks for ensuring mutual exclusion while operating on shared memory locations. All locks in the program are non-re-entrant. i.e. if a thread holds a lock l, then it cannot re-acquire lock l without releasing it. If a thread is unable to acquire a lock, it blocks until the lock becomes available. The minimum value of x and the minimum value of y together for which execution of p can result in a deadlock are:
A.	x = 1, y = 2

Consider the following snapshot of a system running n concurrent processes. Process i is holding Xi instances of a resource R, 1 ≤ i ≤ n. Assume that all instances of R are currently in use. Further, for all i, process i can place a request for at most Yi additional instances of R while holding the Xi instances it already has. Of the n processes, there are exactly two processes p and q such that Yp = Yq = 0. Which one of the following conditions guarantees that no other process apart from p and q can complete execution?

An operating system uses the Banker’s algorithm for deadlock avoidance when managing the allocation of three resource types X, Y, and Z to three processes P0, P1, and P2. The table given below presents the current system state. Here, the Allocation matrix shows the current number of resources of each type allocated to each process and the Max matrix shows the maximum number of resources of each type required by each process during its execution. AllocationMax XYZXYZP0001843P1320620P2211333 There are 3 units of type X, 2 units of type Y and 2 units of type Z still available. The system is currently in a safe state. Consider the following independent requests for additional resources in the current state:REQ1: P0 requests 0 units of X, 0 units of Y and 2 units of ZREQ2: P1 requests 2 units of X, 0 units of Y and 0 units of ZWhich one of the following is TRUE?
