A. If the coil moves vertically upward, it will not cut the magnetic field lines and will not generate induced current, so A is wrong;

B. If the coil moves horizontally to the right, it will cut the magnetic field lines. Induction lines will produce induced current, so B is correct;

C. The vertical axis that bypasses point O rotates in the horizontal plane and will not cut the magnetic induction lines and will not produce induced current, so C is incorrect. ;

D and ad side rotate as the axis, which will cut the magnetic field lines and generate induced current, so D is correct.

That’s why I chose BD.
