The correct answer is D) try to lubricate the line. Explanation: When using or caring for natural-fiber ropes, such as manila or cotton, it is generally not recommended to try to lubricate the line. Natural fibers do not require lubrication and can actually be damaged by the application of lubricants. Lubricants can deteriorate the natural fibers over time, reducing the strength and integrity of the rope. Instead, the recommended practices are to periodically reverse turns on winches to prevent kinking, use chafing gear to protect against wear, and thoroughly dry the line before stowing it to prevent mildew or rot.
