JEE Main 2021 Physics question

Seawater at a frequency f = Hz, has permittivity and resistivity = 0.25 m. Imagine a parallel plate capacitor is immersed in seawater and is driven by an alternating voltage source V(t) = sin(ft). Then the conduction current density becomes times the displacement current density after time t = s . The value of x is. (Given: NmC)
