The correct answer is B) Wire rope should be condemned if the outside wires are worn to one-half their original diameter. This is correct because the U.S. Coast Guard regulations state that wire rope should be condemned and replaced if the outside wires are worn down to one-half their original diameter. This is a key criterion for determining when a wire rope has become unsafe and must be taken out of service. The other options are incorrect: A) Moisture in the fiber core is not a direct criterion for condemning wire rope, as long as the outside wires are not excessively worn. C) The direction of coiling wire rope has no bearing on whether it should be condemned or not.
