A Correct answer
Explanation

Magnetic dip is the angle between Earth's magnetic field lines and the horizontal plane, and it is maximum at the magnetic poles. At the poles, the magnetic field lines are nearly vertical, causing maximum dip angle. This extreme dip is why magnetic compasses become unreliable and exhibit significant errors near the poles, requiring reference to other navigation systems in polar regions.
