Final answer:
The source of power often derives from an exchange relationship where one person or organization provides valuable resources to others.
Step-by-step explanation:
The statement that 'The source of power often derives from an exchange relationship in which one person, department, or organization provides scarce or valued resources to other people, departments, or organizations' is true.
In many social and organizational contexts, power is obtained by controlling and providing resources that others need or desire. This exchange relationship creates a power dynamic where the provider of the resources has influence and control over the recipients.
For example, a manager in a company who controls the budget and allocates resources to different departments has power over those departments because they depend on the resources to function effectively.
