A schedule is called __________ if it is conflict equivalent to a serial schedule.

In a schedule S having 4 transactions executed concurrently. The order of their operation is given below. Find out whether the given schedule is serializable or not?R1(A), R2(B), W2(A), W3(C), R4(C), R3(A), W3(B), R4(A), W2(B), W4(B), W3(A)

Let Ri(z) and Wi(z) denote read and write operations on a data element z by a transaction Tjr respectively. Consider the schedule S with four transactions. S: R4(x) * R2(x) * R3(x) * R1(y) * W1(y) * W2(x) * W3(y) * R4(y) Which one of the following serial schedules is conflict equivalent to S?
