What is the state of a clause with one unassigned literal?
Answer: D
With every other literal false, the remaining one must be true if the clause is to be satisfied, so the assignment is forced rather than chosen. Cascading such forced assignments is unit propagation, which dominates the run time of a modern solver. The other descriptions apply to different clause states. Distinguishing the four states a clause may be in is the whole of the bookkeeping a satisfiability solver performs.
