Which of the following is described as an environmental risk factor?

• A. Living near toxic waste disposal sites
• B. Regular exercise
• C. Sunbathing
• D. Balanced diet

Answer: (A)

Environmental risk factors are elements in the surroundings that increase exposure to hazards and the chance of health problems. Living near toxic waste disposal sites fits this because contaminants can spread through air, water, and soil, leading to exposure to harmful chemicals and associated health risks. In contrast, regular exercise and a balanced diet are protective lifestyle choices that improve health, while sunbathing is a behavior that increases UV exposure rather than an environmental feature of the surrounding area.
