In the pole-dominance model for the two-body nonleptonic decays of charmed mesons [ital D][r arrow][ital PV] and [ital D][r arrow][ital VV], it is shown that the contributions of the intermediate pseudoscalar and the axial-vector meson poles cancel each other in the annihilation diagrams in the chiral limit. In the same limit, the annihilation diagrams for the [ital D][r arrow][ital PP] decays vanish independently.
