The correct answer is B) Six by nineteen regular-lay filler wire rope. The accepted standard for wire rope falls used in connection with lifeboat gear is six by nineteen regular-lay filler wire rope. This is specified in the regulations governing the construction and equipment of lifeboats, which require the use of this type of wire rope for lifeboat falls to ensure adequate strength and durability. The other options are incorrect because they do not meet the regulatory standard. Option A (six by twenty-four improved plow steel wire rope) and Option D (six by thirty-seven preformed fiber-core wire rope) are not the specified type. Option C (six by seven galvanized wire rope) is a different construction that may not have the same load-bearing capacity or resistance to wear and corrosion as the required six by nineteen regular-lay filler wire rope.
