As it pertains to graphical tools used to visualize task scheduling in project management, what statement best represents the difference between a Gantt chart and a PERT chart?

Correct Answer: Option B — The PERT chart (which is a line diagram) makes it easy to visualize task dependencies and milestones, whereas the Gantt chart (which is a bar chart) makes it easy to visualize progress with respect to an actual calendar.

PERT charts use network diagrams to display task dependencies and critical paths, whereas Gantt charts utilize horizontal bar structures mapped against a calendar for chronological progress visualization.
