   Every CSS property must end with a semicolon; here, 'display: none' misses it.

2. Step 2: Verify other options

   Media type '@media print' is correct, class selectors use '.', and 'display: none' is valid in print styles.

3. Final Answer:

   Missing semicolon after 'display: none' -> Option C

}

D. @media print {
nav { font-size: 12pt; }

}

Solution

1. Step 1: Identify correct media query for print styles

   Print styles must be inside @media print { ... } to apply only when printing.

2. Step 2: Check style rules for hiding nav and changing font size

   @media print { nav { display: none; } body { font-size: 12pt; } } hides nav with display: none; and sets font size on body inside print media query, which is correct.

3. Final Answer:

   @media print { nav { display: none; } body { font-size: 12pt; } } -> Option B

4. Quick Check:

   Print styles inside '@media print' with correct selectors [OK]

Common Mistakes:

• Placing print styles outside '@media print'
• Using '@media screen' instead of print
