Correct Option is (B)

Explanation:

Work of cohesion per unit surface is equal to 2.

where is the interfacial energy.

Work of cohesion is the surface free energy which is generated when a column of a pure liquid is divided into two equal parts.

Work of cohesion is reperented by .

Lesser the magnitude of work of cohesion, more will be the spreading of the liquid.

thats how its supposed to be
