What is the answer? Should be B

Please Explain the reason behind

I don't understand how an induced Magnetic Field will cause the coil to move.

thanks for helping

Is an electrically induced magnetic field somehow different from a magnetic field produced by a permanent magnet?

When a magnet moves through the coil of wire, a current is induced in the wire. When current is flowing through a wire, a magnetic field is generated around the wire. If another magnetic field is present, they will interact.

B is true if the coil of wire is shorted. The dB/dt linking the coil will develop a voltage around and hence a current in the wire that opposes the field of the magnet.
