A Correct answer
Explanation

Surface tension is the cohesive force that causes liquid droplets to minimize their surface area by assuming a spherical shape. Among the options, surface tension is the correct physical phenomenon responsible for this behavior. Viscosity relates to fluid flow resistance, density to mass per volume, and kinematic viscosity to viscosity divided by density.
