When a line is subject to wear where it passes through a mooring chock, it should be __________.

Correct Answer: Option D — wrapped with chafing gear

Chafing gear is the industry-standard protective measure for lines passing through chocks. It acts as a sacrificial barrier against the abrasive surfaces of the ship's structure, significantly extending the service life of the mooring line and ensuring it remains capable of holding the vessel's design load.
