Identify the incorrect statement regarding a superconducting wire

Options

A. Transport current flows through its surface
B. Transport current flows through the entire area of crossection of the wire
C. It exhibits zero elactrical resistivity and expels applied magnetic field .
D. It is used to produce large magnetic field

Answer

B

Explanation

In superconductors, the current flows on the surface so that it exactly cancels the magnetic field inside the metal .
