Final answer:
The correct components of Kelley's covariation model are A) Consistency, B) Distinctiveness, and D) Consensus - these are used to determine attribution style.
Step-by-step explanation:
The components of Kelley's covariation model that are used to determine a person's attribution style are A Consistency, B Distinctiveness, and D Consensus. Consistency refers to whether an individual behaves the same way in similar situations over time. Distinctiveness pertains to whether the individual behaves differently in different situations. Consensus involves whether others would behave similarly in the same situation. Therefore, the correct answers are A, B, and D. Constancy and Reliability are not part of Kelley's covariation model.
