  2. adhesion

  3. surface tension

  4. atmospheric pressure

C Correct answer
Explanation

Surface tension is the cohesive force between liquid molecules that causes water droplets to minimize their surface area. A sphere has the minimum surface area for a given volume, which is why small water droplets naturally form spherical shapes.
