Answer:
D). Field lines circle the Earth from east to west.
Step-by-step explanation:
A microscopic force or gigantic magnetic field surrounds the Earth which functions as a force field that guards the planet against the radiations released from space. This magnetic field is characterized by the alignment of the North and South poles with the axis of rotation. Thus, the magnetic field lines of the Earth surround or circle of the Earth from East to West. Therefore, option D is the correct answer.
