To vertically distribute selected objects on a slide, which function in PowerPoint should be utilized?

To vertically distribute selected objects on a slide in PowerPoint, utilizing the "Align to Slide" function is the correct approach. This function helps to arrange multiple selected objects evenly across the vertical axis of the slide, ensuring that they are spaced out proportionally and aesthetically.

When you select multiple objects and use the "Align to Slide" option, you can choose various alignment settings, including vertical distribution. This aligns the objects properly so they do not overlap and maintain uniform spacing, enhancing the overall presentation layout.

In contrast, the other functions listed do not specifically address vertical distribution. For example, "Distribute Horizontally" would space objects evenly along the horizontal axis rather than the vertical one. "Center Objects" focuses on aligning objects to the center, which does not involve spacing them out vertically. "Align to Grid" snaps objects to a grid layout without necessarily achieving even vertical distribution, which can lead to unintended placements that do not consider the overall slide space. Thus, the "Align to Slide" function is essential for achieving the desired vertical spacing among selected objects.
