The correct answer is: A. Blinks diagonal
A transition effect is a visual effect that is used to transition from one scene to another. Some common transition effects include dissolves, fades, wipes, and cuts.
A dissolve is a transition effect in which one scene gradually fades out while another scene gradually fades in. A fade is a transition effect in which one scene fades out completely before the next scene fades in. A wipe is a transition effect in which one scene is replaced by another scene, often in a linear or circular motion. A cut is a transition effect in which one scene is immediately replaced by another scene.
Blinks diagonal is not a transition effect. It is a type of animation effect in which an object appears to blink on and off.
