Social or psychological environment includes which factors?

• A. Physical health
• B. Personal ability
• C. Personal ability, alertness, age, fatigue
• D. Noise

Answer: (C)

The main idea here is that the social or psychological environment is about internal states and demographic factors that shape how a person thinks, feels, and behaves in social settings. The factors listed—personal ability, alertness, age, and fatigue—cover what a person can do, how mentally ready they are, and how their age and energy level influence perception and decision-making. Together, they affect interactions, motivation, and safety in social contexts, which is why this set best represents the social/psychological environment.

Physical health describes bodily health, which is more about the physical condition than social or mental factors. Personal ability alone is incomplete because it misses how alertness, tiredness, and age also change performance and interaction. Noise relates to the physical surroundings and sensory input, not to the social or psychological state the question targets.
