Final answer:
A company run by the great-grandchildren of the founder would be considered to be managed by Generational succession. Other options do not accurately represent this form of business management, which includes kinship and family lineage but centers on the inheritance of a management or leadership role.
Step-by-step explanation:
If a company is run by the great-grandchildren of the founder, it would be considered to be managed by Generational succession (B). This term refers to the practice where management responsibility is passed down through generations within a family. In this scenario, the great-grandchildren have inherited the governance of the company in line with the principles of kinship and family lineage, which are important concepts in sociology and anthropology. Kinship is the social bond based on common ancestry, marriage, or adoption, which is a central organizing principle in most societies. In the context of a family business, this would be akin to 'career inheritance' where family members follow in the professional footsteps of their predecessors.
The other terms listed do not accurately describe the management by descendants in a family business. Cousin contortion isn't a recognized term in any application, while kinship management and family lineage are general terms and do not specifically denote the action of management succession within a family-run business.
