ill-frammed question it is.  A Schedule has been given So, One could ask Either Conflict Equal Serial Schedules or Conflict Equal Schedules. To ask Conflict Serializable schedules, One should Provide Transactions and then ask. Here, 3 transactions are given so 6 Possible Serial Schedules. Would be unnecessarily lengthy if had been asked Conflict Serializable schedules.
