The FTIR spectrum indicates the presence of a carboxylic acid (broad peak around 3000 cm\u207b\u00b9 and a strong peak at 1700 cm\u207b\u00b9), while the 1H NMR spectrum shows complex splitting patterns that suggest specific hydrogen environments. By analyzing the spectral data and comparing it to the provided candidates, we conclude that the correct compound is CH3C(H)(C2H5)C(H)(C2H5)CH2COOH."}
