According to state law, a company must carry workmen's compensation insurance if it has how many or more employees?

In South Carolina, a company is required to carry workers' compensation insurance if it has four or more employees. This law is designed to provide financial protection and medical benefits to employees who might suffer injuries while performing their job duties. By mandating coverage for businesses with this threshold of employees, the state ensures that a significant number of workers are protected, given that many businesses, especially smaller ones, may not have the financial resources to cover work-related injuries without insurance.

The requirement helps safeguard the welfare of employees and promotes a safer work environment, as employers are more inclined to adhere to safety regulations when insurance is involved. Thus, the correct answer highlights an important aspect of labor law and employee rights within the state.
