The correct answer is: A. Form Selector
To apply an AutoFormat to an entire Form, you must first select the Form Selector. The Form Selector is the small box in the upper-left corner of the Form that contains the name of the Form. Once you have selected the Form Selector, you can then apply an AutoFormat to the entire Form.
Option B, Document tab, is incorrect because the Document tab is used to format the document as a whole, not individual Forms. Option C, Detail section, is incorrect
because the Detail section is only one part of a Form, and you cannot apply an AutoFormat to just one part of a Form. Option D, Any control, is incorrect because you cannot apply an AutoFormat to just one control, you must select the entire Form.I hope this helps!
