Molecules of fluid get attracted means - cohesion.
Molecules of different fluid get attracted means - adhesion.
Molecules of different fluid get attracted means - adhesion.

What do we consider molecules?

Cohesion means force of attraction b/w same molecules and adhesion means force of attraction b/w diffrent molecules.
So D is the correct answer.
So D is the correct answer.

It is Adhesion because it is fluids. In the same fluid, it is cohesion.
The answer is C.
The answer is C.

A correct answer is an option : D Cohesion because it is clearly mentioned in the question that molecules get attracted means to "each other". So, it's cohesion.

Let me make it clear and simple:
Adhesion occurs between two different Molecules.
Cohesion occurs between two same Molecules.
In the Question, it says "FLUIDS" not "FLUID"
Which means different Fluids/Molecules.
So the Correct Answer is (C) Adhesion.
Adhesion occurs between two different Molecules.
Cohesion occurs between two same Molecules.
In the Question, it says "FLUIDS" not "FLUID"
Which means different Fluids/Molecules.
So the Correct Answer is (C) Adhesion.

Cohesion- attractive force between similar bodies. (Here water molecules are similar bodies).
Adhesion- attractive force between two different bodies (water attached to the glass).
And, mercury in the glass does not wet it or doesn't wet when kept on the table because of very strong cohesive force between mercury molecules there is no adhesive force between mercury molecules and glass i.e. why it didn't wet it.

Correct answer is cohession.

I think the given answer is right because here it is not mentioned that whether they are molecules of same fluids are of different fluids, if we consider the common example of water in a glass, where the glass inner side gets wet, this is because of the water molecules gets attracted towards the glass, which says adhesion occurred.

According to the question it says molecule of fluids (which is plural) that means more than one fluid.
Cohesion: The attraction between a molecule of a fluid (single fluid) ie, singular.
Adhesion: Attraction between different molecules (more than one fluid or fluid to container) ie, plural.
So, the answer is ADHESION.
Cohesion: The attraction between a molecule of a fluid (single fluid) ie, singular.
Adhesion: Attraction between different molecules (more than one fluid or fluid to container) ie, plural.
So, the answer is ADHESION.
