What BEST defines adhesion.
A
Water molecules bonding to each other due to the hydrophobic nature of water.
B
Water molecules bonded to other other surfaces due to the transparency of water.
C
Water molecules sticking to each other due to the polarity of water.
D
Water molecules sticking to other surfaces due to the polarity of water.
Explanation: 

Detailed explanation-1: -Adhesion of Water Molecules. The adhesion property is also often observed in water. This is because the adhesion of water allows it to “stick” to many surfaces and objects. The adhesion of water is best explained as the ability of water to stick to other surfaces through the creation of weak surface bonds.

Detailed explanation-2: -Water molecules stick to other materials due to its polar nature. This property is called adhesion.

Detailed explanation-3: -Adhesion refers to the tendency of water molecules to be attracted, or ‘’stick”, to other substances. This is a result of the covalent bond between the two hydrogen atoms and the one oxygen atom in the water molecule. In a covalent bond, the electrons of the bonded atoms are shared.
