(b) blocks the passage of current through the materials

(c) leaks the current through the materials

(d) reverses the direction of current in the materials

I have been asked this question in an interview.

My question is from Electrical Conducting Materials in chapter Electrical Engineering Materials of Design of Electrical Machines

Answer 1

Right option is (a) allows the passage of current through the materials

Easy explanation: The basic property of conducting materials is to allow the flow of charges, and align them in a particular direction. The process is nothing but the flow of current in the materials.
