To change the vertical alignment of text to middle aligned, which option should be selected?

To change the vertical alignment of text to middle alignment, selecting the option "Align Text Middle" is the appropriate choice. This option specifically targets vertical alignment within a text box, allowing the text to be centered vertically between the top and bottom of the text area.

Understanding vertical alignment is key in formatting text within shapes or text boxes, as it affects how the text is positioned in relation to the available space. When the vertical alignment is set to middle, it ensures that regardless of the height of the text box, the text itself will consistently remain centered vertically, providing a balanced and aesthetically pleasing appearance. The other options primarily focus on horizontal alignment or do not specifically address vertical alignment at all.
