We investigate the possibility of testing the factorization hypothesis in nonleptonic exclusive decays of the B meson. In particular, we consider the nonfactorizable B̄0→D(*)+Ds(*)- modes and B̄0→D(*)+(π-, ρ-) known as well-factorizable modes. By taking the ratios Β(B̄0→D(*)+Ds(*)-)/Β[B̄0→D (*)+(π-,ρ-)], we find that under the present theoretical and experimental uncertainties there is no evidence for the breakdown of the factorization description for heavy-heavy decays of the B meson.
