A falling drop of water acquires spherical shape due to
-
atmospheric pressure
-
gravitational force
-
surface tension
-
capillary rice
C
Correct answer
Explanation
Surface tension minimizes the surface area of a liquid for a given volume, causing water droplets to become spherical (a sphere has minimum surface area). Atmospheric pressure and gravitational force act externally, while 'capillary rice' is a typo for 'capillary rise' (a different phenomenon).
