Guys let me tell you that correct answer must be cohesion.
(This question is taken from A book name Objective civil engineering(By R Agor) in which the given answer is Adhesion that is wrong).

Cohesion : The force of attraction between the molecules of a liquid by virtue of which they are bound to each other to remain as one assemblage of particles is known as the force of cohesion.

Reymon said:   4 years ago
According to the question; fluids means not only liquid but also gases. And liquid also different types. So different Types of fluids get attracted called adhesive property.

Answer should be cohesion.

Because molecules of liquids are attracted by cohesion & molecules of liquids are attracted to the molecules of solid due to adhesion.

Jivan shahi said:   4 years ago
Answer C is correct because similar molecules gets attract cohesion.

But the question says fluids molecule (fluids means Liquid and gases) its different molecules.

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.

@All.

Here is the explanation.

If the same molecules asked then the answer is cohesion.

If a different molecule is asked then the answer is adhesion.

Abdullahfani said:   7 years ago
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.

Muhammad zaheer said:   5 years ago
Its C, because the question is molecules of fluids not fluid (which means different types of liquid molecules are attracted by adhesion).

Akshay said:   7 years ago
If it attracts towards itself then options d is correct. If it attracts to different material or object then the option C is correct.
