The correct answer uses dashes to set off additional information that interrupts the main thought. Dashes create emphasis and can replace commas, parentheses, or colons for dramatic effect. For example: 'My brother—the one who lives in Paris—is visiting next week.' The other options misuse dashes by placing them where commas or no punctuation would be better. Remember that dashes should enclose non-essential information that you want to emphasize.
