Suppose that 2PC is use as the commit protocol. Consider the following for a distributed transformation T with coordinator and to sites P1 and P2. C aborts. C commits. Consider the following case (in each failure case assume that this is the only in the system): (a) The coordination site for T fails after writing a commit log record but before sending any message to participating sites. (b) The coordination site for T fails right after sending a prepare massage to sites (c) A participating site for T fail before sending a ready message. (d) All participating sites sent ready message to coordinator. For each of the scenarios specify a group of above cases that can occur in that scenario. Your answer should be represented as the following table (please, do not provide any explanation)
