Explanation

A Flowchart (B) graphically represents how elements of a system interrelate by using standardized symbols and arrows to map processes, decisions, and relationships between components - making it the go-to tool for visualizing system structure and workflow dependencies.

Why the distractors are wrong:

• A. Control chart - tracks process variation over time against control limits; it monitors stability, not system relationships.
• C. Run chart - displays data points plotted in time sequence to spot trends; it's about time-based patterns, not system interrelationships.
• D. Pareto chart - ranks defects or causes by frequency (the 80/20 rule); it prioritizes problems but doesn't show how system elements connect.

Memory tip: Think of a flowchart as a "map of how things flow and relate" - the word flow implies movement between connected elements, which is exactly what system interrelationships describe.
