Correct Answer:
B. Skin cancer
The correct answer is Skin cancer. Ultraviolet (UV) radiation from the sun or artificial sources like tanning beds can damage the DNA in skin cells. This damage can lead to mutations, causing cells to grow uncontrollably and form cancerous tumors.
- Global warming is primarily caused by the emission of greenhouse gases, not directly by UV rays.
- Acid rain results from sulfur dioxide and nitrogen oxides reacting with water in the atmosphere.
- Air pollution is a broad term for harmful substances in the air; while UV can contribute to smog formation, it doesn't directly cause the overall phenomenon of air pollution in the same way it directly causes skin cancer.
