Which of the following is FALSE with respect to the Gantt chart and network diagram?

• Gantt charts visually show the duration of tasks, whereas a network diagram visually shows the sequence dependencies between tasks.

• Gantt charts visually show the time overlap of tasks, whereas a network diagram does not show time overlap but does show which tasks could be done in parallel.

• Gantt charts visually show the time overlap of tasks, whereas a network diagram shows time overlap but does show which tasks could be done in parallel.

• Some forms of Gantt charts can visually show slack time available within an earliest start and latest finish duration.
