Which of the following factors is considered extrinsic to the job?

Extrinsic factors are those that originate outside of the job itself and are typically tangible rewards or incentives that can motivate an employee. Salary is a prime example of an extrinsic factor because it is a monetary compensation provided for the work performed and is not inherently linked to the job responsibilities or the employee's personal satisfaction with their work.

In contrast, responsibility, growth, and achievement are intrinsic aspects, as they relate more to personal fulfillment, professional development, and the sense of accomplishment an employee gains from their work. Responsibility pertains to the duties associated with the job; growth refers to opportunities for advancement and learning within the role; and achievement focuses on personal or team success in accomplishing goals. These factors are driven by the individual's experiences and perceptions relating to their work environment and self-efficacy, rather than outside incentives. Thus, salary is considered the correct answer as it embodies the concept of extrinsic motivation in the workplace.
