We present a study of rare decay modes B+ → D$$^{+}_{s}$$ℎ0, B+ → D$$^{*}_{s}$$⁢+ℎ0, and B+ → D+⁢ℎ0, where ℎ0 denotes the neutral meson η or K0, using a data sample of (772 ±10) ×106 B$$\overline{B}$$ events produced at the Υ⁡(4⁢S) resonance. The data were collected by the Belle detector operating at the asymmetric-energy KEKB collider. We find no evidence for these decays, so we set upper limits at the 90% confidence level on the branching fractions of , , and D+⁢ℎ0 decay modes. Along with these rare decay modes, we report improved measurements of the color-suppressed decay branching fractions $$\mathscr{B}$$⁡($$\overline{B}$$0 →D0⁢η) =(26.6 ±1.2 ±2.1) ×10-5 and $$\mathscr{B}$$⁡($$\overline{B}$$)0 →D0⁢ $$\overline{K}$$0) =(5.6 ±0.5 ±0.2) ×10-5. The first and second quoted uncertainties are statistical and systematic, respectively.
