Answer

Answer:

A warm, moist air mass collides with a cold, dry air mass.

Brief Explanations:

Tornadoes form when warm - moist and cold - dry air masses meet, creating instability and rotation in the atmosphere. The other options are not the main cause of tornado formation. Water vapor condensation is part of thunderstorm formation but not the sole cause of tornadoes. Wind over ocean water forcing vapor upward is more related to hurricanes. Sudden air - pressure changes can be a result rather than the main cause of tornadoes.
