  This paper presents the two body weak nonleptonic decays of B-mesons emitting
vector (V) and vector (V) mesons within the framework of the diagrammatic
approaches at flavor SU(3) symmetry. We have investigated exclusive two body
decays of B-meson using model independent quark diagram scheme. We have shown
that the recent measurement of the two body exclusive decays of B-mesons can
allow us to determine the magnitude and even sign of the QD amplitude for B VV
decays. Therefore, we become able to make few predictions for their branching
fractions.
