Assume, There is schedule for transactions T0, T1 and T2 which is given below. Schedule : read1A; read2 B; write1C; read3B; read3C; write2 B; write3A Where the subscript denotes the transaction number. Assume that the time stamp of T0 ,T1 and T2 is 9:05AM,9:10 AM and 9:20 AM

respectively. The transactions are using timestamp-based protocol. Assume transactions are executed and if failure occurs which transaction need to be roll back, give the reason.
