Hint: Cohesive and adhesive forces are associated with bulk properties, and hence the terms are not applicable to the atomic and molecular properties. When a liquid comes in contact with a surface where water and other molecules can be absorbed (such as the walls of a graduated cylinder or a tabletop), both cohesive and adhesive forces will act on it.
Complete Solution: The Term, Cohesive Force is referred to as for the collective intermolecular forces responsible for bulk properties of liquid resisting separation. These attractive forces exist between the molecules of the same substance. The term adhesive force is referred to as attractive forces between unlike substances such as mechanical force and electrostatic force. These theories of Cohesion force and Adhesion Force were proposed by Dixon and Jolly (\[1894\]).
So the right answer is Option A.
Additional Information:
The cohesive strength of a luting agent or adhesive, regardless of its chemical composition, is determined by a number of molecular forces: the chemical bonds within the adhesive material, chemical bonds due to crosslinking of the polymer(s) within a resin-based material, intermolecular interactions between the adhesive molecules, and mechanical bonds and interactions between the molecules in the adhesive. Adhesion is the characteristics of different particles and/or surfaces to adhere or bond to one another and can be divided into three basic types. Specialized adhesion is achieved by the molecular interaction between the adhesive and also the substrate surface. The intermolecular force produces specific adhesion, though this is divided into three different types, as the chemical adhesion, dispersive adhesion, and diffusive adhesion, to which are added mechanical effects ineffective adhesion.
Note: According to the theory of Dixon and Jolly, water molecules are always in a continuous movement and are strongly attracted to each other, forming a continuous column of water xylem elements and are transported upwards towards other parts. These attractive forces are Cohesive Force and Adhesive Force.
