Surface tension always tends to minimize the surface area.

Surface tension is the final result. But the actual cause is the property cohesion. The force due to cohesion holds the molecules together.

Hi, I am Confused between Surface tension and Cohesion.

What is to be the right answer? Please tell me.

@Aman.

Cohesion is the intermolecular force of attraction between the particles of liquid.

On the other hand surface tension is a property of liquid due to unbalanced Force at the top surface of the liquid.

I think cohesion resists the tensile force.

Mechasi said: (Jul 24, 2019)  
In my opinion, cohesion would be the most accurate answer because the force attraction of molecules due to cohesion is more than the force of attraction of molecules due to surface tension. Therefore as a result surface tension would offer the least resistance to tensile force as compared to cohesion.

Yes, the Surface tension is tensile force while cohesion resists that force.
