The electric flux through a certain area of a dielectric medium is $$\phi = \left(8.00\times10^3\right)t^4$$ in SI units. The displacement current through that area is $$12.5\,\text{pA}$$ at a time $$t = 20.0\,\text{ms}$$. The dielectric constant of the dielectric medium is

A

22.1

B

5.52

C

55.2

D

2.76
