Step-by-step explanation:
To increase the font size of selected text, you can choose the Increase Font Size button, which is typically located on the mini toolbar.
The mini toolbar is a small toolbar that appears near the selected text and provides quick access to common formatting options, such as font size, font color, and text alignment. The Increase Font Size button is usually represented by a larger "A" with an arrow pointing upwards, and it can be used to increase the font size of the selected text by one level.
Alternatively, you can also increase the font size of selected text using the shortcut menu, which is a menu that appears when you right-click on the selected text. The shortcut menu typically provides access to a range of formatting options, including font size.
Therefore, the correct answer is:
