What is the outcome of clicking the Distribute Vertically option in PowerPoint?

Choosing the Distribute Vertically option in PowerPoint results in images or objects being spaced evenly along the vertical axis of the slide. This means that if you have multiple images or objects selected and you apply the Distribute Vertically command, PowerPoint calculates the total space from the top to the bottom of the selected objects and positions them so that there is equal spacing between each one.

This feature is particularly useful for ensuring a neat and professional look in presentations by creating uniformity in the arrangement of elements. It helps to enhance visual balance and alignment, making it easier for the audience to follow along with the content. The other options do not accurately describe the function of this command, as stretching images, aligning them horizontally, or positioning them at the top does not pertain to the vertical distribution of objects.
