Query: First Estimates of Nonleptonic $B_c \to AT$ Weak Decays   We obtain the first estimates of branching ratios for the weak decays of
$B_c$ meson decaying to two orbitally excited mesons namely, axial-vector meson
($A$) and tensor meson ($T$), in the final state. We calculate $B_c \to T$
transition form factors using the Isgur-Scora-Grinstein-Wise II framework and
consequently predict branching ratios of $ B_c \to AT $ decays in
Cabibbo-Kobayashi-Maskawa favored and suppressed modes.
