Correct:
D
Explanation
The deflection of wind is caused by the Coriolis force, which is an apparent force generated by the Earth's rotation. According to Ferrel's Law, winds are deflected to the right of their path in the Northern Hemisphere and to the left of their path in the Southern Hemisphere.
- Temperature and Pressure differences create the pressure gradient force that initiates wind movement, but they do not cause the lateral deflection.
- Magnetic Field does not influence the direction of atmospheric winds.
The Coriolis force is directly proportional to the angle of latitude; it is strongest at the poles and absent (zero) at the equator. This deflection is crucial in determining the direction of trade winds, westerlies, and the rotation of cyclones.
