Q.what would you choose to create a pre-formatted style in MS PowerPoint?
a) Slide sorter view
b) Slide Layout
c) Slide Transition
d) Slideshow
Explanation: Slide Design should be the correct answer. Slide sorter view does not offer any pre-formatted styles. Slide Layout allows you to choose 'what element will be positioned where' in the slide, but it does not include any pre-formatted styles. Slide transition is the effect applied for the duration when current slide exits and new slide enters in the show. The slideshow is when you run your presentation.

However, if this is the question asked in the exam and I wish to answer, I would choose Slide Layout as near to the correct answer.
