What does the <big> tag in HTML define?

The tag in HTML is specifically used to define text that should be displayed in a larger font size than the surrounding text. When this tag is applied, it provides a visual emphasis by increasing the font size, making it suitable for highlighting important information or headings within the content.

Other HTML tags serve different purposes: a line break is typically achieved using the
tag; hyperlinks are defined by the tag; and bold text is often represented with the or tags. The distinct function of the tag makes it clear that its primary role is related to text size enhancement, underscoring why the choice referring to large font text is the correct interpretation of the tag’s purpose.
