Answer» RIGHT choice is (C) Non-deterministic POLYNOMIAL time The best explanation: Although any given solution to an NP-complete problem can be validated quickly in polynomial time; there is no way to efficiently LOCATE a solution to begin with. The UNIQUE characteristic of NP-complete problems is that no fast solution to them is known and hence NP-complete problems are said to be non-deterministic polynomial time.
