A parallel plate capacitor made of circular plates is being charged such that the surface charge density on its plates is increasing at a constant rate with time. The magnetic field arising due to displacement current is: 

(1) Zero at all places 

(2) Constant between the plates and zero outside the plates 

(3) Non-zero everywhere with maximum at the imaginary cylindrical surface connecting peripheries of the plates 

(4) Zero between the plates and non-zero outside                                                                       (NEET-2025)
