B - when the warm, moist air and the cool, dry air meet, they create instability in the atmosphere
The answer is - condensate.
When the warm air with water vapor rises up in the atmosphere it reaches a point were temperatures drop, and this causes the water vapor to start the process of condensation, so the water vapor turns from gas to liquid, the forming of the clouds starts, and after that rain starts to fall.
