Which statement about a cold front affects weather?

A cold front acts as a boundary where a cooler, denser air mass advances and wedges under the warmer air ahead of it. This rapid lifting destabilizes the warm air, often triggering convection and producing showers or thunderstorms. When the front passes, you typically feel a sharp drop in temperature and a shift in wind as cooler air moves in. The statement describing rapid lifting of warm air with showers or thunderstorms and a sharp temperature fall captures how a cold front affects weather. The other descriptions don’t fit: gradual warming with mild rain is more like a warm front, fog-only scenarios aren’t the typical outcome of a cold front, and no precipitation contradicts the usual frontal forcing.
