Answer: a
Explanation: The generic current density equation is J = I/A and the point form of Ohm’s law is J = σ E. On equating both and substituting E = V/L, we get V = IL/σ A = IR which is the Ohm’s law

's law, we can derive the expression for electric field in terms of current density and conductivity:

Electric field (E) = conductivity (σ) times current density (J)

or

E = σJ

This equation relates the strength of the electric field to the flow of electric current through a material. It is commonly used in the study of electrical conductivity and helps to understand how different materials conduct electricity.
