To insert a new slide into an existing presentation, which option should you choose?

To insert a new slide into an existing presentation, the option to click the new slide arrow is the most effective choice. This action provides direct access to the slide insertion functionality, allowing you to add a new slide seamlessly. When you click on the new slide arrow, it typically reveals a drop-down menu from which you can select various slide layouts to best fit the content you plan to present.

Choosing this option ensures that you can quickly and easily expand your presentation by adding additional slides without disrupting your workflow. The new slide feature is designed specifically for this purpose and is a standard part of most presentation software interfaces, making it the most intuitive and efficient option for the task at hand.

Other options, such as clicking the layout button or selecting a comparison layout, are related to modifying the structure or design of existing slides rather than adding new ones. Beginning a slide show is not applicable to the task of inserting a slide, as it initiates the presentation instead of editing it. Thus, clicking the new slide arrow is the recommended method for inserting additional slides.
