Solution

The correct option is B Circles centered on the wire
The magnetic field due to a long wire is in the direction, the fingers of our right hand would curl, if we wrap them around the wire, such that our thumb is in the direction of the current. So,the magnetic field lines of a long straight current carrying wire can be described by circles centered on the wire.
