Regarding liquid the wrong statement among the following is 

a
Due to surface tension it occupies minimum surface area.
b
Relative motion between the adjacent layers of the liquid opposes by viscous force.
c
Rain drops are spherical in shape due to viscous dragging force.
d
Mass of the liquid rise in a capillary is directly proportional to its radius.

detailed solution

Correct option is C

rain drops are spherical in shape due to surface tension as liquid surface try to occupy minimum surface area and for a given volume sphere has minimum surface area.
