Liquid drop is always taking a spherical shape because of the following factors acting on it while falling freely.
1) Gravitational force acting on every molecule of the liquid.
2)Atmospheric pressure acting all around the surface of the drop.
3)Inter- molecular attraction and bonding.
4)Surface tension
EXPLANATION.
a)By gravitation liquid is freely falling, hence experience the weightlessness.In other words effect of gravitation is nullified due to free fall.
b)Because atmospheric pressure is acting all around the liquid mass, mass of the liquid is pushed towards the center of the mass.
c)Inter-molecular forces are more in and around the center of the mass. Hence this also contributes something to become the falling liquid mass to be spherical.
d) Surface tension is also acting towards the center of the mass of the liquid.
By all the above reason falling liquid is spherical.
Note- Falling liquid in large volume is not in spherical shape.

They don't. When they're falling they take on a teardrop shape.
Sitting on a flat surface they are disc shaped unless there is a lot of surface tension then they are somewhere between sphere and disc.

It has to do with surface tension. A sphere has a property that it has maximum volume with minimum surface area. And when you have a liquid it tends to want to have minimal surface area.

at that shape the it can resist maximum against the force of gravity.,
