The correct answer is C) arrange it on deck in long bights. Faking a line refers to the method of arranging a line (rope) on deck in long loops or bights rather than tightly coiling it. This allows the line to run out freely and smoothly when needed, such as when docking a vessel or launching a boat. Arranging the line in long bights on the deck is the proper technique for "faking" a line, as it prevents tangles and ensures the line can be paid out quickly and efficiently. The other options are incorrect because: A) stowing the line below deck would not allow it to be accessed and deployed easily, B) putting a whipping on the end of the line is a different technique, and D) coiling the line down on deck in a tight coil would not allow it to run out as freely as the correct method of faking in long bights.
