Which of the following best describes the major influences driving behavior?

• A. Genetic determinants alone.
• B. Economic and educational factors.
• C. Biological, psychological, and social influences.
• D. Cultural expectations alone.

Answer: (C)

Behavior is shaped by an interplay of multiple influences rather than a single cause. The best description recognizes biological, psychological, and social factors all contributing to actions and choices. Biological factors include genetics, brain function, and physical health; psychological factors cover thoughts, emotions, motivations, and personality; social factors involve family, culture, socioeconomic context, and environmental influences. Together, these domains interact to drive behavior, which is why this broad, integrative view is more accurate than focusing on just one area. For example, a career decision can be shaped by innate interests (biological/psychological), personal beliefs and coping styles (psychological), and access to resources or cultural expectations (social). The other descriptions are too narrow, as they isolate behavior to one domain and ignore how the other domains interact and shape outcomes.
