Which statement is true about serif fonts?

• A. Sans-serif fonts appear more modern and easier to read on screens.
• B. They have small lines at the ends of letters.
• C. Serif fonts have small lines at the ends of letters.
• D. Serif fonts are always used for digital interfaces.

Answer: (C)

Serif fonts are defined by the small decorative strokes at the ends of their letterforms. These little lines, or serifs, come from traditional typography and can help guide the eye along lines of text, which is why serif faces are common in printed body text and convey a more classic look. The statement that serif fonts have small lines at the ends of letters matches this defining feature, making it the correct choice. The other options describe sans-serif characteristics or make broad claims about digital use that don’t apply to serif fonts.
