If the drop is small enough, it is a perfect sphere. A sphere is the geometrical shape that
has the smallest surface area for its volume. The drop takes this shape because water
molecules tend to stick to each other. So, when not confined by a container, and with
nothing around it to distort its shape, a very tiny water drop is perfectly round like a
ball because the water molecules are pulling inward toward each other.
For a fixed volume, a sphere is the shape with the lowest surface area to volume ratio. Surface tension is minimized when the drop forms a sphere, and molecules always tend toward the position which minimizes energy.

liquid drops are spherical coz the cohesion between their molecules pulls them into the shape of the least possible surface area which is a sphere in air

Rain drops are not spherical. They are more "tear-drop" shaped, elongated in the direction in which they fall, as the result of air resistance .

cohesion/ cohesive forces
Surface tension
Surface tension. It is caused by cohesion, or that molecules tend to feel attracted to like molecules.
Yes, that's true.

The reason mercury droplets are spherical is because they do easily wet other surfaces. For this reason, mercury forms spheres, which have the smallest possible ration of surface area to volume.

Its surface tension hold it in a logical shape (why is a bubble spherical?)

It is surface tension.
