The goal is to identify the correct final products of two reactions based on the given reactants. The candidates provide different structures for products A and B, and the task is to analyze these structures to determine which ones correctly represent the outcomes of the reactions. This requires knowledge of reaction mechanisms and the ability to visualize organic structures."}
