Which option lets you apply a specific effect to an animation?

The choice that allows you to apply a specific effect to an animation is the "Effect Options." This feature provides users with a dropdown menu or settings panel where you can choose from a variety of effects tailored for the current animation being applied, such as entrance, emphasis, or exit effects. By selecting "Effect Options," you gain control over parameters like the direction from which an object appears or how it behaves during the presentation. This granularity allows for precise customization of animations to suit storytelling or emphasis needs in your slides.

Other choices, while they may relate to animations, do not specifically focus on applying distinct effects. "Animation Settings" generally refers to a broader category of settings that encompass various aspects of animation, including the timing and order of animations. "Customize Animation" is an older term that was used in previous versions of PowerPoint and is often replaced with the current animation panes, focusing on modifying the sequence or timing rather than applying specific effects. "Edit Effects" is also not a standard term used in the latest versions of PowerPoint, and generally doesn't pertain to applying new effects to animations. Each of these focuses more on managing or modifying rather than specifically applying a distinct effect.
