D Correct answer
Explanation

N95 respirators are recommended for preventing the spread of H1N1 (swine flu) as they filter out at least 95% of airborne particles. The other options (N007, W580i, SN59) are not standard mask designations - they appear to be nonsensical or made-up codes designed to test if you know the correct terminology.
