  Recently reported anomalies in various $B$ meson decays and also in the
anomalous magnetic moment of muon $(g-2)_\mu$ motivate us to consider a
particular extension of the standard model incorporating new interactions in
lepton and quark sectors simultaneously. Our minimal choice would be
leptoquark. In particular, we take vector leptoquark ($U_1$) and
comprehensively study all related observables including ${(g-2)_{\mu}},\
R_{K^{(*)}},\ R_{D^{(*)}}$, $B \to (K) \ell \ell' $ where $\ell\ell'$ are
various combinations of $\mu$ and $\tau$, and also lepton flavor violation in
the $\tau$ decays. We find that a hybrid scenario with additional
$U(1)_{B_3-L_2}$ gauge boson provides a common explanation of all these
anomalies.
