A Correct answer
Explanation

As a warm front approaches, the barometric pressure consistently falls. This pressure drop occurs because the warm air mass is less dense than the cold air it's replacing, and the gradual lifting of warm air creates a region of lower atmospheric pressure. The pressure typically reaches its minimum point just as the warm front passes, then begins to stabilize or slowly rise afterward.
