Which option disables scroll bars for a form in Design view?

To disable scroll bars for a form in Design view, you would use the Property Sheet Format tab. This part of the Property Sheet provides various formatting options specific to forms, including settings for scroll bars. Within the Format tab, you can find the Scroll Bars property, where you can select options like "None," "Horizontal," or "Vertical" to configure how scroll bars behave when the form is displayed.

The other options do not directly relate to scroll bar settings. The Form Header property settings pertain to handling specific elements in the header section of the form rather than the general scroll bar configuration. The Form Properties dialog encompasses multiple settings but is broader in scope, making it less specific compared to directly adjusting properties from the Format tab. Lastly, the Control Source property adjustment relates to data connections for controls on the form, which does not affect the appearance or functionality of scroll bars. Thus, the Property Sheet Format tab is the most appropriate choice for disabling scroll bars in Design view.
