The correct answer is option C, an electric power line
Explanation:
Whenever a current flows through a wire , magnetic field is produced along with it in a perpendicular direction of the motion of flowing current. Now a compass is a device in which its needle shows motion towards the magnetic field. Thus, When an electric wire is placed near to it, its needle start showing deflection toward the magnetic field of electric wire.
The earth rotates from West to East or if you want another way of saying it, counter-clockwise. It rotates from West to the East because the earth's Western Hemisphere (West) rotates to the Eastern Hemisphere, (East).
