The task is to analyze the final product's structure to determine its molecular symmetry group. The reactions include nitration, oxidation, and a reaction with acetone and sodium hydroxide. The goal is to identify the correct symmetry group from the given options, which is C2h, indicating a specific type of symmetry in the molecular structure of product C."}
