To determine the correct answer to the question, we need to understand the concepts of motivation and job security.

Motivation refers to the underlying reasons or drives that compel an individual to behave or act in a certain way. There are two types of motivation: intrinsic and extrinsic.

Intrinsic motivation involves engaging in an activity because it is inherently satisfying or enjoyable to the individual. This type of motivation is driven by internal factors, such as personal interest, enjoyment, or a sense of accomplishment.

Extrinsic motivation, on the other hand, involves engaging in an activity to obtain external rewards or avoid negative consequences. This type of motivation is driven by external factors, such as money, fame, or job security.

Job security, as the name suggests, refers to the assurance or guarantee of continued employment and income stability. It is a factor that is often valued by individuals because it provides stability and peace of mind.

Now, returning to the question, the worker in an automobile assembly line who chooses this type of work because of the job security it entails is likely to be extrinsically motivated. They value the external reward or benefit of job security and are driven by the desire to have a stable income and employment.
Therefore, the correct answer is "Extrinsically motivated."
