• A. Developmental Theory
• B. Systems Theory
• C. Maslow's Theory
• D. Biopsychosocial Theory

Answer: (A)

Systems Theory is the idea that all parts of the body are connected and influence one another, so health and illness arise from patterns of interaction within the whole person. This perspective helps nurses assess how changes in one system can affect others and why care often targets the person as an integrated unit rather than isolated organs. Maslow's Hierarchy of Needs, while a valuable theory, deals with human motivation and needs, not how physiological systems function together. Developmental Theory focuses on growth stages across the lifespan, and Biopsychosocial Theory looks at biological, psychological, and social factors influencing health, but not the specific interdependence of bodily systems. So the statement aligns with Systems Theory.
