If you thrust a magnet into a closed loop of wire, the loop will have current in it. So the correct option is B.
A magnet is a body with a magnetism that can attract different irons that can be given naturally or artificially. Magnets can have their magnetic field continuously and this field can attract materials or repel them, this will depend on the magnetic permeability of the compound. The magnetic field of the images will be oriented towards the south pole and the north pole and each of these will be attracted by their opposites.
Not all magnets have permanent magnetism, this depends on whether they are going to be magnetized to be permanent or if they will only have temporary functionality.
By pushing a magnet in a closed circuit of wire, a magnetic field will be generated in which a current will flow in the turns of wire.
Therefore, we can confirm that the correct option is B. have current in it.
