The TDA Action Out of Turn rule currently reads as follows:
Rule 44-A: Any action out of turn (check, call, or raise) will be backed up to the correct player in order. The OOT action is subject to penalty and is binding if action to the OOT player does not change. A check, call or fold by the correct player does not change action. If action changes, the OOT action is not binding; any bet or raise is returned to the OOT player who has all options: call, raise, or fold. An OOT fold is binding. See Illustration Addendum.

C: Action is back on C, what are his options?
