Step-by-step explanation:
The act of instituting a change in the process of managing resistance is called unfreezing.
Unfreezing refers to the process of preparing individuals or organizations for change by helping them recognize and understand the need for change. It involves breaking down the existing mindset and beliefs that may hinder the acceptance of change.
Once unfreezing has occurred, the next steps in the process of managing resistance include moving and refreezing. Moving involves implementing the change, while refreezing involves stabilizing the change and ensuring it becomes the new status quo. So, the correct answer to the question is C) unfreezing.
