Final answer:
To apply a transition to a slide, choose one of the given options such as Fade, Cut, Slide, or Zoom, based on the effect you wish to achieve in your presentation.
Step-by-step explanation:
To apply a transition to the selected slide, you would need to select one of the options given. If we were to choose from the options A) Fade, B) Cut, C) Slide, and D) Zoom, it would depend on the desired effect for the presentation. For example, a 'Fade' transition involves the slide slowly dissipating to reveal the next one, while a 'Cut' transition is an immediate change from one slide to the next without any effect. A 'Slide' transition makes it look like the next slide is pushing the current one off the screen, and a 'Zoom' transition makes the slide appear to zoom in or out as it changes. The question does not specify which transition to apply, hence it is up to you to choose based on your preference or presentation style.
