520 _ _ |a We report the first observation of ${B}^{0}\to X\left(3872\right)\left({K}^{+}{\pi }^{-}\right)$ and evidence for ${B}^{+}\to X\left(3872\right)\left({K}^{0}{\pi }^{+}\right)$. We measure the product of branching fractions for the former to be $\mathcal{B}\left({B}^{0}\to X\left(3872\right)\left({K}^{+}{\pi }^{-}\right)\right)×\mathcal{B}\left(X\left(3872\right)\to J/\psi {\pi }^{+}{\pi }^{-}\right)=\left(7.9±1.3\left(\text{stat}\right)±0.4\left(\text{syst}\right)\right)×1{0}^{-6}$ and find that ${B}^{0}\to X\left(3872\right){K}^{*}\left(892{\right)}^{0}$ does not dominate the ${B}^{0}\to X\left(3872\right){K}^{+}{\pi }^{-}$ decay mode. We also measure $\mathcal{B}\left({B}^{+}\to X\left(3872\right)\left({K}^{0}{\pi }^{+}\right)\right)×\phantom{\rule{0ex}{0ex}}\mathcal{B}\left(X\left(3872\right)\to J/\psi {\pi }^{+}{\pi }^{-}\right)=\left(10.6±3.0\left(\text{stat}\right)±0.9\left(\text{syst}\right)\right)×1{0}^{-6}$. This study is based on the full data sample of $711\text{}\text{}{\mathrm{fb}}^{-1}$ ($772×1{0}^{6}B\overline{B}$ pairs) collected at the $\mathrm{Υ}\left(4S\right)$ resonance with the Belle detector at the KEKB collider.
