The IR spectrum shows characteristic bands indicating the presence of hydroxyl and carbonyl groups, while the NMR data provides information about the hydrogen environments in the molecule. By analyzing the chemical shifts and splitting patterns in the NMR spectrum, we can deduce the structure of the compound. The correct identification leads us to conclude that the compound is Methyl 4-aminobenzoate."}
