      abstract     = {Production fraction ratios of B$^+$, B$^0$, and
                      B$^0_\mathrm{s}$ mesons are measured in proton-proton
                      collisions at $\sqrt{s}$ = 13 TeV using a special data set
                      recorded in 2018 with high-rate triggers designed to collect
                      an unbiased sample of $10^{10}$ b hadrons with the CMS
                      experiment at the LHC. These data allow the use of the
                      open-charm decays of B mesons
                      (B$_\mathrm{(s)}$$\to$$π$D$_\mathrm{(s)}$) where the D
                      meson decays into fully hadronic final states. Production
                      fraction ratios as functions of B meson transverse momentum
                      ($p_\mathrm{T}$) and rapidity ($y$) are measured using the
                      open-charm decays in the kinematic range of 8
                      $\lt$$p_\mathrm{T}$$\lt$ 60 GeV and $\lvert y \rvert$$\lt$
                      2.25. In addition, the same data are used to measure the
                      relative production fraction ratios with the charmonium
                      decay channels (B$_\mathrm{(s)}$$\to$ X$\,$J/$ψ$ with X
                      indicating a K$^+$, K$^*$(892)$^0$, or $ϕ$(1020) meson)
                      with the J/$ψ$ meson decaying into a pair of muons. By
                      utilizing known branching fractions, precision theoretical
                      calculations, and the open-charm results, the production
                      fraction ratios in the charmonium samples are determined
                      with an absolute normalization for the first time. These
                      results also improve several world-average values of the
                      ratios of branching fractions of B meson decays to
                      charmonium and open-charm states. Finally, we test isospin
                      invariance in B meson production in proton-proton collisions
                      and observe that it holds within the experimental
                      precision.},
