Final answer:
The root metaphor for the psychodynamic paradigm is a Clock, relating to the complex interplay of psychological processes within the mind.
Step-by-step explanation:
The root metaphor for the psychodynamic paradigm is C) Clock. Psychodynamic theory is heavily influenced by the works of Sigmund Freud, who often compared the mind to a complex mechanical system.
