According to Kelly, a person's construct system

The correct answer reflects the essence of Kelly's Personal Construct Theory, which posits that individuals perceive and interpret their experiences through a framework of bipolar constructs. Essentially, people organize their thoughts and experiences around pairs of opposites, such as "good-bad," "happy-sad," or "strong-weak." This finite set of constructs allows individuals to make sense of their world by categorizing and contrasting different experiences.

In this theory, it’s not an infinite set of constructs because while we can create many constructs based on our experiences, they still stem from a limited number of opposing dimensions that help us navigate our understanding of reality. The notion of a finite number of opposite constructs encapsulates how people simplify complex information into manageable and meaningful dichotomies.

The other options do not accurately encapsulate Kelly's ideas. For instance, the idea that the construct system is limited to personal experiences overlooks the influence of broader cultural and social contexts in shaping one's constructs. Similarly, the view that it does not include future possibilities is misleading since Kelly emphasized that constructs can help individuals forecast and anticipate future events based on their understanding of the past and present.
