Which statement best describes what happens when a front passes?

When a front passes, the air mass at the surface changes in several ways all at once. The temperature and dew point shift as the boundary moves and the new air mass replaces the old one, reflecting the different moisture and warmth of each side. Winds rearrange direction as the front passes, often flipping from one prevailing flow to another. The surface pressure pattern also changes—typically it’s associated with a shifting pressure tendency as the front moves through the area. So the best description is that temperature and dew point shift across the front; winds shift direction; and the pressure pattern changes. The other statements are too limited: fronts bring more than just precipitation changes, and the wind direction change isn’t restricted to a single direction like northerly only.
