Abstract We report measurements related to hadronic B decays to final states that contain charm mesons. The analyses are performed on an 62.8 fb1 data set collected by the Belle II experiment at a center-of-mass energy corresponding to the mass of the Υ(4S) resonance. The measurements reported are for the decay modes BD0h, BD0h, B¯0D+h and B¯0D+h, where h=π or K. These modes are either signal or control channels for measurements related to the unitarity triangle angle γ in direct or time-dependent CP-violation measurements. The reported observables are the ratios between the BD()K and BD()π decay rates, which are found to be in agreement with previous measurements.
