Which of the following is a domain of quality of life?

• A. Nutrition
• B. Physical
• C. Education
• D. Sleep

Answer: (B)

Quality of life is viewed through different domains that capture distinct areas of well‑being. The physical domain centers on how health and bodily functioning affect everyday life—energy, mobility, strength, pain, and fatigue—shaping what a person can do on a daily basis. Because this domain directly represents bodily health and functioning, it is considered a domain of quality of life.

Nutrition and sleep matter greatly for overall well-being, but they are typically seen as components that influence the physical domain rather than standalone QoL domains. Education, on the other hand, relates more to knowledge, opportunities, and socioeconomic factors than to health-related functioning. So the physical domain best fits the common framework for quality of life.
