What tag is used to force text to a new line?

The <br> tag is designed specifically to create a line break within text. When placed in the HTML code, it forces the following content to start on a new line without creating additional space around it, which is essential for controlling the layout of text in a web page. This is particularly useful for formatting poetry, addresses, or any other content where line breaks are necessary for readability or style.

Other tags listed have different purposes. The <p> tag defines a paragraph, which inherently includes space above and below the text block, thereby not solely functioning to force a new line without added spacing. The <div> tag is used to create a block-level container that can hold larger sections of content and applies CSS styles; it does not create line breaks by itself. Lastly, the <line> tag does not exist in standard HTML and is not used for text formatting. This makes the <br> tag the only correct choice for forcing text to a new line while maintaining the integrity of the surrounding content.
