The “wrong-sign” D0 → K+π−π0 decay is one of the most promising channels at Belle II, as this can be produced through two interfering processes: a direct doubly Cabibbo-suppressed decay of the D0 meson, or through D0-  ̄D0 mixing followed by a Cabibbo-favored decay of the D0 meson. In this work, we report the WS-to-RS ratio of the “wrong-sign” D0 → K+π−π0 decay in the simulation of the integrated luminosity of 1 ab−1 at Belle II. The Belle II is the upgraded experimental facility at SuperKEKB, KEK, Japan. This study will be used to measure the mixing and CP Violation of the “wrong-sign” D0 → K+π−π0 decay.
