Linking pin structure of the organisation was proposed by

The correct answer is: D. Likert

Rensis Likert was an American social psychologist who developed a system of management called System 4. System 4 is a participative management style that emphasizes teamwork, cooperation, and employee involvement. Likert's linking pin structure is a key component of System 4. The linking pin structure is a network of overlapping groups that connect different levels of the organization. This structure allows for communication and coordination between different levels of the organization, and it helps to create a sense of unity and purpose among employees.

Scott, Kahn, and Sherwood are all psychologists who have made significant contributions to the field of organizational behavior. However, they did not develop the linking pin structure of the organization.
