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_(5)H_(12)O STRUCTURE:

A. 1.0 ppm (singlet), 1500-1600 cm^(-1) (strong)
B. 2.3 ppm (doublet), 2800-3000 cm^(-1) (sharp)
C. 3.7 ppm (triplet), 1200-1300 cm^(-1) (medium)
D. 4.9 ppm (multiplet), 3000-3500 cm^(-1) (broad)
