Choice B.

Work Step by Step

A current is induced only when the magnetic flux through the loop is changing. The magnetic field near a long, current-carrying straight wire is inversely proportional to the distance from the wire. Moving the loop parallel to the wire, keeping it the same distance from the wire, means that the flux through the loop stays constant. No current is induced.
