The IR spectrum shows characteristic bands indicating the presence of hydroxyl and carbonyl groups, while the NMR spectrum provides information about the hydrogen environments in the molecule. By analyzing the data, we conclude that the compound is Ethyl 4-aminobenzoate, as it matches the expected spectral features and molecular formula."}
