Solution

The correct option is C

BrF3


The explanation for the Correct option

(C) Bromine trifluoride (BrF3) possesses a non-dipole moment .

The electronegativity gap between bromine and fluorine atoms assures polarity across the Br-F bond in this molecule, which comprises three fluorine atoms encircling one bromine atom. The polar bond's dipole moment is never zero.

The explanation for the incorrect options

NH4+, PCl5, XeO3F2all are showing zero dipole moment.
