Query: An Isospin Analysis of $CP$ Violation in $B_{d}\to D\pi$, $D^{*}\pi$ and
  $D\rho$   By use of current experimental data, we carry out an isospin analysis of the
weak decays $B\rightarrow D\pi, D^{*}\pi$ and $D\rho$. It is found that only in
$B\rightarrow D\rho$ the strong phase shift of two different isospin amplitudes
can be approximately neglected. We derive some useful relations between the
$CP$-violating measurables and the weak and strong transition phases, and
illustrate the different effects of final-state interactions on $CP$ violation
in $B_{d}\rightarrow D\pi, D^{*}\pi$ and $D\rho$.
