Step-by-step explanation:
The correct answer to this question is A. Theme. Every theme includes a color scheme and a font scheme that affect style options. In the context of design and document formatting, a theme is a predefined set of colors, fonts, and effects that can be applied to a document or presentation to give it a consistent and professional look. When you apply a theme, it automatically updates the color scheme and font scheme of the document, allowing you to easily change the overall style without manually modifying each element.
