The correct answer is A) Chain chasers will not work with piggyback anchors. The primary disadvantage of a permanent chain chaser system is that it is not compatible with piggyback anchor arrangements. Chain chasers are designed to deploy a single anchor chain, but piggyback anchors require the ability to deploy two separate anchor rigs. Using a chain chaser system would prevent the vessel from being able to effectively utilize a piggyback anchor configuration, which is a common technique for improving anchoring capability. The other answer choices do not accurately describe the key limitations of a permanent chain chaser system.
