Molecules of fluid get attracted due to cohesion.
Example: When you drop a Mercury in to the horizontal surface, it gets gathered due to cohesion. And if you drop a water in surface, it gets wets and flow in all direction, it is due to adhesion.
Mercury is a non-wetting fluid and water is a wetting fluid. So right answer is the option 'C'.
