The Proximity Compatibility Principle (PCP) suggests that information that needs to be compared or integrated should be displayed close together or in a way that supports easy comparison. Option A, where each speed is represented by the height of a bar connected by a line, allows for direct and immediate comparison, adhering to the principles of PCP by visually integrating the two pieces of information in a manner that supports easy comparison.
