The Attempt at a Solution

Options a) and c) are correct . But I don't understand how non magnetic metal reacts to the magnetic field .

Is it in some way related to ferromagnetism ? But then either both b) and d) should be correct or both incorrect ?

If it is about ferromagnetism then relative motion between the magnet and sheet should not play any role .

Option d) is about relative motion between magnet and the sheet . I doubt whether it is in some way related to change of flux .
