The presence of a nitro group and ether linkage influences the chemical shifts and splitting patterns observed in the NMR spectrum. The task is to identify the correct set of 1H NMR data from the provided candidates that accurately reflects the expected chemical environment of the protons in the compound. The correct answer is the one that aligns with the expected shifts for the aromatic protons and the protons on the ether group."}
