\nThe correct option is C, vertical plane.
\n<\/section>\n
\nThe magnetic meridian at any point on the Earth’s surface is an imaginary vertical plane that passes through the geographic location and the Earth’s magnetic poles (or more precisely, along the local direction of the Earth’s magnetic field lines). The angle between the magnetic meridian and the geographic meridian (the vertical plane containing the geographic North and South poles) is called magnetic declination.

\nA compass needle, free to rotate in a horizontal plane, aligns itself with the horizontal component of the Earth’s magnetic field, pointing towards the magnetic north pole along the magnetic meridian. If the needle is free to rotate vertically as well, it dips, aligning with the full magnetic field vector within the magnetic meridian plane.
