Which of the Following Maxwell equation is for nonexistence of isolate

1.	Which of the Following Maxwell equation is for nonexistence of isolated magnetic charge?(a) ∇×E=-\(-\frac{\partial B}{\partial t}\)(b) ∇×H=J(c) ∇.D=ρv(d) ∇.B=0The question was posed to me in a job interview.The query is from Radiation topic in section Radiation, Baluns & Polarization of Antennas
Answer» Correct choice is (d) ∇.B=0 For explanation I would SAY: Gauss law for magnetic field states that the net FLUX out of any closed surface is zero. ∇.B=0 This is satisfied only when two different poles of magnet exist. So this Maxwell EQUATION proves for the NONEXISTENCE of the isolated magnetic charge. Faradays Law: ∇×E=\(-\FRAC{\partial B}{\partial t}\) Amperes Law: ∇×H=J Gauss Law for electric field: ∇.D=ρv
