Query: Final State Interactions and Delta S=-1, Delta C=\pm 1 B--decays   The final state interactions (FSI) in Delta S=-1, Delta C=\pm 1, decays of
B-meson are discussed. The rescattering corrections are found to be of order of
15-20%. The strong interaction phase shifts are estimated and their effects on
CP-asymmetry are discussed.
