Which statement describes the characteristics of chronic health hazards?

• A. They are temporary and reversible
• B. They cause only acute symptoms
• C. They affect only nonliving objects
• D. They are permanent and irreversible

Answer: (D)

Chronic health hazards are defined by effects that linger long after exposure and are often not reversible. That’s why permanent and irreversible best describes them. Unlike acute hazards, which cause immediate effects that may go away once exposure stops, chronic hazards lead to long‑lasting health problems, sometimes resulting in permanent damage or disease. They affect living beings, since health hazards relate to the body's response to harmful substances or conditions, not inanimate objects. So, the idea of being temporary and reversible or only causing acute symptoms doesn’t fit chronic hazards, and the notion of affecting nonliving objects isn’t relevant to health effects on people.
