Based on the molecular formula, we can determine that there are 16 boron atoms in the compound. Since boron does not exhibit any NMR signals, we can exclude options II and IV because they both contain boron atoms in the structure. 
Option I does not have any sulfur atoms, which is inconsistent with the molecular formula that contains two sulfur atoms. 
Option III contains all the atoms present in the molecular formula (excluding hydrogen atoms) and has a peak in the IR spectrum at 3200-3600 cm-1, which suggests the presence of an -OH or -NH group. The given NMR spectral data also confirms the presence of an -NH group with a chemical shift at around 4.5 ppm. Therefore, the structure of compound X is most likely III.
