B. An owner-manager
An owner-manager is a person who owns and runs a small firm, such as a small business or a family-owned enterprise. This person is responsible for the overall management and operations of the firm, including making strategic decisions, managing finances, and overseeing employees. They are also the owner of the firm, and they often have a significant personal investment in the business.
A manager-owner is similar to owner-manager but with a slight difference in term of the focus on ownership or management. An enterprise worker is someone who works in a company and a professional adapter is someone who can adapt to different roles and situations.
