Which of the following describes a collection of fonts, colors, and effects you can apply to an entire document?

The term that describes a collection of fonts, colors, and effects that can be applied to an entire document is known as a theme. A theme provides a cohesive and visually appealing design by ensuring that all the elements of the document have a consistent look and feel. This includes harmonizing the color palette, font choices for headings and body text, and other stylistic effects across the document, which helps enhance readability and aesthetics.

Using a theme simplifies the process of formatting a document, as it allows users to apply a unified design without manually adjusting each element individually. This approach is particularly beneficial for maintaining visual consistency in professional documents, presentations, or any multi-page work where a uniform style is desired.

While other options like styles and templates contribute to document formatting, they serve different purposes. Styles refer to predefined sets of formatting choices for specific elements (like headings or paragraphs), templates provide structured layouts for documents but do not necessarily dictate the overall design aspects, and layouts pertain more to the arrangement of content on a page. Therefore, themes are specifically focused on the overarching visual style and coherence of an entire document, making them the correct choice in this context.
