This means that while the initial size may be set by the template or slide layout, users have the flexibility to resize the organization chart object as needed.
Option A: Is determined by the presentation design and cannot be changed is incorrect because PowerPoint allows users to modify the size of objects, including organization charts.
Option C: Is dependent on the amount of text within the organization chart is incorrect because the size of the chart is primarily determined by its design and formatting, not just the amount of text.
Option D: b and c is incorrect because Option C is not completely accurate regarding the size dependency on text.
