Solution

The correct option is C ClF3
PCl5 is a symmetrical molecule. It's net dipole moment is zero.
ClF3 has distorted geometry due to the presence of lone pairs on Cl atom, μ0.
XeF4 is square planar and is a symmetrical molecule.
C2H5CCC2H5 is also symmetrical and hence the net dipole is zero.

Option B is correct.
