Which of the following is NOT a typical dispersion pattern for cryogenic containers?

Explanation:
Cryogenic releases form visible fog because the extremely cold gas chills and condenses moisture in the surrounding air. This creates a low-lying cloud that tends to hug the ground and drift with the wind. When wind is present, the gas spreads downwind as a plume, extending the dispersion in the direction of airflow. Early in the release, the gas can expand in all directions around the vent, producing a roughly hemispherical pattern. A cone pattern, however, implies a directed, jet-like cone from a nozzle, which isn’t how cryogenic vent releases behave—they disperse broadly and mix with ambient air rather than forming a sustained conical jet.
