An organization that is not defined by, or limited to, the horizontal, vertical, or external boundaries imposed by a predefined structure is called a/an:
A. Matrix organization
B. Boundaryless organization
C. Divisional organization
D. Virtual organization
E. Entrepreneurial organization

Answer:
B. Boundaryless organization

Explanation:
A boundaryless organization is one that seeks to remove the typical barriers found in traditional organizational structures. These include vertical boundaries (between levels of hierarchy), horizontal boundaries (between functional departments), and external boundaries (between the organization and its suppliers or customers). This concept allows for a more flexible and responsive organization.
