What are common barriers to implementing ECPL?

B is the correct answer because it encompasses a comprehensive understanding of the multiple dimensions that can hinder the implementation of Effective Communication and Performance Leadership (ECPL). Personal barriers may include individual resistance to change, lack of motivation, or misunderstandings related to the objectives of ECPL. Organizational barriers could involve inadequate support from management, insufficient training resources, or a lack of established protocols to facilitate communication and leadership practices. Environmental barriers might relate to the workplace culture, external pressures, or physical workspace conditions that impact how communication and leadership are carried out. Since these categories cover a broader range of possible obstacles than the other options, they accurately reflect the complexity of challenges faced when implementing ECPL.
