Which of the following is considered an internal influence on behavior?

The correct choice highlights an internal influence on behavior as it pertains to intrinsic motivations and personal characteristics. Greed embodies an individual's internal desires and motivations that can dictate their actions and decisions. It originates from within a person and can significantly impact their behavior, often guiding them toward actions that may benefit themselves at the potential expense of others.

In contrast to internal influences, factors like media coverage and local citizens represent external influences that can shape behavior based on societal perceptions and pressures. Agency subculture relates to the shared values and norms within an organization, also considered an external factor impacting collective behavior rather than individual motivations. Greed, being an internal component of personal psychology, serves as a strong motivator for actions driven by self-interest and personal gain.
