What is a common characteristic of swim jigs and bladed jigs when being retrieved?

Swim jigs and bladed jigs are specifically designed to mimic the motion of fleeing baitfish, which makes option B the correct choice. Both types of jigs can incorporate dynamic movements that resemble how baitfish escape predators in their natural environment. This characteristic is appealing to predatory fish, provoking them to strike.

In contrast, dragging jigs along the bottom may not effectively convey the fleeing action; this technique is more suitable for other types of lures intended for bottom fishing. Claiming that these jigs are fished with no action is misleading, as the effectiveness of swim jigs and bladed jigs heavily relies on their action during retrieval. Additionally, their effectiveness is not confined to just slow-moving water; they can be used in various water conditions. Thus, the focus on their design to imitate fleeing baitfish clearly sets them apart in their retrieval method.
