Explanation / Answer

1] A cold air mass moves in under a warm air mass is correct option.

Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone.  The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation.
