What is the correct sequence to apply a transition and sound to a slide in PowerPoint?

The correct sequence of applying a transition and sound to a slide in PowerPoint is to first apply the transition, then add the sound, and finally apply it to all slides as needed. This approach ensures that the transition effect is established first, allowing you to preview how the slide will animate during the transition. Adding sound afterward allows you to select a sound that complements the transition, enhancing the overall effect without complicating the initial transition setup.

By applying the transition first, you can visualize the timing and flow of the slide change and make any necessary adjustments before incorporating audio, which can impact the overall timing and feel of the presentation. Finally, applying the transition and sound to all slides streamlines the process if consistency is desired across multiple slides, making it more efficient to finalize your presentation.

The other options may disrupt this logical sequence, either by applying sound too early before establishing how the slide changes will look or by enforcing transitions before optimizing those settings for all slides. Ultimately, starting with the transition ensures a better-integrated presentation experience.
