Identify the wrong statement.

Displacement current is also a source of magnetic field like conduction current. Gauss law in electrostatics states that electric field lines can form closed loops. Microwaves are relevant waves in telecommunication. Microwaves are used in navigation of aircrafts.

Gauss law in electrostatics states that electric field lines can form closed loops.

Electric field lines originate from positive charge and terminate at a negative charge. They do not form closed loops.
