The Correct Option is C
Solution and Explanation
Electric field lines can form closed loops in the case of a time-varying magnetic field, as described by Faraday's law of induction. Option (C) depicts concentric circles, which accurately represent the electric field induced by a changing magnetic flux perpendicular to the plane of the circles. The direction of the arrows (indicating the field direction) would correspond to the right-hand rule applied to the changing magnetic field. Since a magnetic field due to a current carrying wire can be represented as concentric circles, and a time varying magnetic field can produce a time varying electric field which can be depicted as concentric circles.
The correct answer is (C) :
