Which toolbar option is used to justify the text on a slide?

To justify text on a slide, the appropriate toolbar option typically focuses on text alignment features. Justifying text means adjusting the spacing so that it aligns evenly along both the left and right margins, creating a clean and organized appearance. This is commonly found under text alignment tools, which offer different alignment options such as left, center, right, and justified.

The other options, while related to text configuration, do not specifically address the need to align text across the slide. Text formatting generally refers to changing the appearance of the text, such as font size and color, rather than its alignment. Font style pertains to the aesthetics of the letters themselves, such as bold or italic, without influencing how the text is positioned on the slide.

The foundational understanding of text alignment is essential for effective slide design, as it enhances readability and overall presentation quality. Therefore, the correct tool for justifying text must be one focused on alignment rather than formatting or styling attributes.
