Provide the different spatial arrangements of $ClF_3$ including its lone pairs.

(A) The central atom $Cl$ in $ClF_3$ has $7$ valence electrons. It forms $3$ single bonds with $F$ atoms and has $2$ lone pairs,resulting in a total of $5$ electron pairs ($sp^3d$ hybridization). According to $VSEPR$ theory,the lone pairs occupy equatorial positions to minimize repulsion,leading to a $T$-shaped molecular geometry as shown in arrangement $(a)$.
