(B) To determine the dipole moment,we analyze the molecular geometry:$1$. $CH_4$: Tetrahedral geometry,symmetrical,dipole moment $= 0$.$2$. $BF_3$: Trigonal planar geometry,symmetrical,dipole moment $= 0$.$3$. $H_2O$: Bent geometry,asymmetrical,dipole moment $
eq 0$.$4$. $HF$: Linear,polar bond,dipole moment $
eq 0$.$5$. $NH_3$: Trigonal pyramidal,asymmetrical,dipole moment $
eq 0$.$6$. $CO_2$: Linear geometry,symmetrical,dipole moment $= 0$.$7$. $SO_2$: Bent geometry,asymmetrical,dipole moment $
eq 0$.Thus,the molecules with zero dipole moment are $CH_4$,$BF_3$,and $CO_2$.The total number is $3$.

The total number of molecules with zero dipole moment among $CH_4$,$BF_3$,$H_2O$,$HF$,$NH_3$,$CO_2$,and $SO_2$ is $ . . . . . . $.
