Answer:
A. after you've created the presentation.
Step-by-step explanation:
A power point presentation is defined as a presentation program where one can create any presentation or design any layout like the photo album slide show to present it to others.
Once the album is created in the PowerPoint, it can be changed by going to the slide show and editing the content of the photo album of the slide show. Thus it is easier to make any changes in the design of the photo album slide show after the presentation have been created.
