The correct answer is: A. Add effect
The Add effect option on the custom animation task pane allows you to apply a preset or custom motion path to an object. A motion path is a line that an object follows as it moves on the slide. You can choose from a variety of preset motion paths, or you can create your own custom motion path.
The Emphasis option on the custom animation task pane allows you to add emphasis effects to an object, such as a grow, shrink, or spin effect.
The Animate now option on the custom animation task pane allows you to start an animation immediately.
I hope this helps!
