Final answer:
Reciprocal determinism explains the interplay between Sarah's optimism and career success.
Explanation:
Reciprocal determinism is the concept that best illustrates the relationship between Sarah's optimism and her successful career accomplishments. This theory, proposed by psychologist Albert Bandura, suggests that a person's behavior is influenced by interactions between their individual characteristics, their environment, and their behavior itself. In Sarah's case, her optimistic outlook contributes to her success, while her accomplishments, in turn, reinforce her optimism, creating a cycle of positivity and achievement.
