Workers differ from one another, and are paid differently, because they have different amounts and types of human capital, allowing them to be more or less productive than other workers.

The answer is option 2

Human capital refers to the skills, knowledge, experience, and abilities that individuals possess, which contribute to their productivity and effectiveness in the workplace. Workers with higher levels of human capital tend to be more productive and efficient, leading to higher wages or salaries.

For example, two employees working in the same role may receive different pay based on their educational background, training, certifications, and experience. The worker with more human capital, such as advanced skills or specialized knowledge, is likely to be more productive and valuable to the employer, resulting in higher compensation.
