The UV-Vis spectrum indicates a strong absorption at 280 nm, which is characteristic of aromatic compounds. The 13C NMR signal at 160 ppm suggests the presence of a carbonyl group (C=O), and the mass spectrum shows a molecular ion peak at m/z = 180. By analyzing these data points, we can conclude that the correct chemical formula is C9H8O2, which corresponds to a compound with a structure consistent with the observed spectral features."}
