  Analysis of charged and neutral B meson decays into pi+ pi- K, K+ K- K and
K0S K0S K0S is performed using a unitary representation of the pi pi and K
anti- K 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 -->
rho(770) K decays.
