What controls the amount of spacing between lines of text?

The correct response is line spacing, which specifically refers to the vertical distance between lines of text within a paragraph. Adjusting line spacing can significantly affect the readability and overall appearance of a document. Proper line spacing helps prevent the text from feeling cramped and allows for easier reading, making it an essential tool in formatting documents effectively.

Text alignment refers to how the text is arranged in relation to the margins of the page—such as left, right, center, or justified—and does not influence the spacing between individual lines. Font size determines how large or small the text appears but does not control the space between lines directly. Paragraph spacing relates to the space before and after paragraphs, which influences how text blocks are separated, but it does not affect the spacing between the lines of text within a single paragraph. Thus, line spacing is the most accurate term to describe the spacing between lines of text.
