Final answer:
The Adaptive Model component in a decision strategy falls under the Decision Analytics category, as it uses machine learning to refine predictions based on historical data.
Step-by-step explanation:
In a decision strategy, the Adaptive Model decision component belongs to the Decision Analytics category. Adaptive Models are a type of decision component that utilize machine learning algorithms to predict future outcomes based on historical data. They are used within a decision strategy to analyze and refine predictions and decisions over time as more data becomes available. This approach is central to the concept of decision analytics, where the goal is to improve decision accuracy and operational efficiency. As such, the correct answer is (a) Decision Analytics category. It is worth noting that predictive models are a broader category that includes other types of predictive analytics, not just adaptive models.
