Kelly's theory is based on the idea that

A) people in a culture construe events in identical ways.
B) future events duplicate past events.
C) personality is unchanging.
D) themes from the past will appear in the future.

Kelly's theory is based on the idea that themes from the past will appear in the future. This is a key aspect of his "personal construct theory," which suggests that individuals' understanding of the world is based on their unique interpretations and constructions of events and experiences. While people may share some common experiences and cultural influences, Kelly believed that each person's subjective understanding of these experiences is different and shapes their individual personality. Thus, his theory emphasizes the potential for growth and change in personality over time.
