Answer:
C. Gantt charts adequately illustrate the interrelationships between the activities and the resources.
Explanation:
Gantt charts are used mainly in project management as they help to visually represent tasks/goals during a specific period of time. It is a great tool to successfully follow and plan a project. However, a Gantt chart won't illustrate the interrelationships between activities and resources, as resources are not a factor in Gantt charts. They do show how tasks relate to each other or overlap each other but not resources.
