We show that in the PQCD approach the B → ρ(ω)K decays display not only the dynamical penguin enhancement, the mechanism responsible for the large branching ratios (BRs) of B → φK decays, but also the importance of annihilation contributions. We find that the CP asymmetries (CPAs) of B → ρ±K∓, B∓ → ρ0(ω) K∓ (class I) are all over 50%.
