Solution

The correct options are
A It has body centred cubic unit cell
B Coordination number of both $C s^{+}$ and $C l^{-}$ ions are eight
$C s C l$ crystallizes in Body centered cubic unit cell with coordination number of both $C s^{+}$ and $C l^{-}$ are $8$ .

$C l^{-}$ are present at body corners.
$C s^{+}$ is present at body centre.

There is one formula unit $C s C l$ present in a unit cell.

Hence, the correct options are $A$ and $B$
