Label all the NMR peaks in proton NMR. In IR, label at least one band which helped you to identify the compound. Molecular Formula: C_(4)H_(8)O_(2) STRUCTURE:

A. 1.2 ppm (singlet), 1700-1800 cm^(-1) (sharp)
B. 2.4 ppm (doublet), 1200-1300 cm^(-1) (medium)
C. 3.6 ppm (triplet), 2800-3000 cm^(-1) (broad)
D. 4.8 ppm (multiplet), 3000-3500 cm^(-1) (strong)
