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'.

Molecules of fluid get attracted due to cohesion you writing and at last you telling answer is C. What is the answer?

It is D .
Or the question should explain whether molecules are attracted towards a different material or towards itself.

The answer should be cohesion, not adhesion.

Fluids means different fluids not one fluid. Different fluids molecules attract due to adhesion. And if written attraction between fluid (note here no 's' at end ) so there having same fluid with differnt molecules and so cohesion.

Actually, both are attractive forces.
Difference is only that adhesive force is an attraction between unlike molecules (eg molecules of water with beaker) and cohesion is between like molecules (molecules of water).

D) cohesion is the answer.

Cohesion isvthe property of a material to attract its molecules whereas.
Adhesion is the property to attract other molecules and threfre water does not attract other molecules. So answer is D.
