The ${}^1\mathrm{H}$ and broadband proton-decoupled ${}^{13}\mathrm{C}$ NMR spectra of compound $\mathrm{A}\left({\mathrm{C}}_7{\mathrm{H}}_{12}{\mathrm{O}}_2\right)$ are shown below. The labels next to each of the resonances in the ${}^1\mathrm{H}$ NMR spectrum signify the integrals and multiplicities observed $(\mathrm{d}=$ doublet, $\mathrm{dd}=$ doublet of doublets, $\mathrm{dt}=$ doublet of triplets, sept $=$ septet. $)$ DEPT 90 and DEPT 135 data are included in the table on the following page. Use this spectroscopic evidence to determine the identity of the compound. Make clear assignments of all resonances to explain your reasoning. ${}^1\mathbf{H}:$ broadband proton-decoupled ${}^{13}\mathrm{C}$ : ${}^1\mathrm{H}$ NMR assignments: ${}^{13}$ C NMR assignments:
