Which term is also known as line breaking?

The correct choice highlights the process whereby text automatically moves to the next line when it reaches the end of a defined margin or text box, which is commonly referred to as word wrapping. This function is crucial in word processing and text editing, as it allows for the creation of visually appealing and organized documents without manual adjustments to line endings.

In contrast, text justification refers to adjusting the spaces between words so that each line of text aligns evenly along both the left and right margins, creating a block of text that appears tidy. Paragraph formatting deals with setting the attributes of paragraphs, such as indentation, spacing, and line height. Text alignment concerns the positioning of text within a document, such as left, center, right, or justified alignment. While all these terms are integral to document production, word wrapping specifically describes line breaking, making it the appropriate answer.
