We have computed the branching ratios of the exclusive pseudoscalar (vector) + tensor modes that are allowed in the decays of the B c meson. The dominant spectator and annihilation contributions in those decays are evaluated using the factorization hypothesis. We find that some of these decay channels, such as B c − → (ρ − , D s * − , D s − )χ c 2 and B c − → π − , have branching ratios of the order of 10 −4 , which seems to be within the reach of forthcoming experiments at the LHC. The inclusive branching fraction of the two-body B c decays involving tensor particles is approximately 1.28 × 10 −3 . At the dynamical level, it is interesting to observe that the exclusive decays B c − → K − (π − ) , π 0 D 2 * − , η' D s 2 * − are dominated by the annihilation contributions.
