Step-by-Step Solution
The complete worked solution.
Every step explained - no skipped algebra.
Cloud droplets initially too small to fall grow larger by colliding and coalescing with other droplets inside clouds. This process, aided by varying air currents, allows droplets to increase in size until gravity overcomes updrafts, causing precipitation.
Final Answer: Option B - Collision and coalescence
