The 1H-NMR and 13C-NMR signals provide crucial information about the hydrogen and carbon environments in the molecule. By analyzing the chemical shifts and splitting patterns in the spectra, we can compare them to the proposed candidates to find the correct structure of compound X. The goal is to match the spectral data with one of the four given candidates."}
