Which statement about fragrance is true regarding environmental and health effects?

• A. Fragrance has no impact on wildlife or air quality.
• B. Fragrance is beneficial to ozone formation and wildlife.
• C. Fragrance dissolves quickly in water and has no ecological effects.
• D. Fragrance is toxic to wildlife and contributes to ozone pollution due to VOCs.

Answer: (D)

Fragrance releases volatile organic compounds (VOCs) into the air. In sunlight, these VOCs react with nitrogen oxides to form ground-level ozone, a key component of smog that can irritate lungs, harm sensitive plants, and degrade air quality. The same VOCs can also enter water systems through washing and disposal, where certain fragrance ingredients show toxicity to aquatic wildlife. This combination—ozone formation and aquatic toxicity—is why fragrances can have notable environmental and health effects. The other statements wrongly imply no impact, a beneficial effect on ozone or wildlife, or no ecological consequences, which doesn’t align with how VOCs behave in the environment.
