Analysis of charged and neutral B meson decays into π+π-K, K+K-K and [Formula: see text] is performed using a unitary representation of the ππ and [Formula: see text] final state interactions. Comparison of the theoretical model with the experimental data of the Belle and BaBar Collaborations indicates that charming penguin contributions are necessary to describe the B → f0(980) K and B → ρ(770)0 K decays.
