A Slide Transition in Microsoft PowerPoint is the visual effect that occurs when one slide changes to the next during a presentation. These effects make presentations more engaging by adding movement between slides. Examples of slide transitions include Fade, Push, Wipe, Split, Morph, and many others available in the Transitions tab.
Slide transitions are applied to an entire slide rather than to individual objects. Users can customize the transition by adjusting its duration, adding sound effects, or setting it to advance automatically after a specified time or on a mouse click. Applying appropriate transitions helps create a smooth and professional flow throughout a presentation.
It is important to distinguish slide transitions from animations. Animations affect individual objects such as text, images, or shapes within a slide, whereas transitions control how one complete slide is replaced by another. Therefore, the effect seen when moving from one slide to the next is called a Slide Transition, making Option B the correct answer.
