Advection fog and upslope fog are both dependent on wind for their formation, making this answer correct.

Advection fog occurs when warm, moist air moves over cooler land or water. The movement of wind is essential in carrying this warm air into contact with the cooler surface, leading to condensation and the formation of fog. This type of fog is common along coastlines, where sea breezes bring moist air over cooler land.

Upslope fog forms when moist air is forced to ascend a slope, such as a mountain. As the air rises, it cools adiabatically, leading to condensation and fog. Again, wind plays a crucial role in moving the air up the slope, creating the conditions necessary for this type of fog to develop.

In contrast, other types of fog such as radiation fog typically form under calm conditions during the night and do not rely on wind to develop. Likewise, ice fog generally occurs in extremely cold temperatures but does not require wind in its formation process. Therefore, the dependence on wind is a distinguishing factor for advection and upslope fog.
