How are cohesion and surface tension related to the chemical properties of water?
a. all are properties related to hydrogen bonding
b. all have to do with ionic interactions.
c. all are results of the structure of the hydrogen atom.
d. all are produced by covalent bonding

The correct answer will be option-A

Explanation:

Cohesion is the property of the water which holds the water molecules together.

The cohesive property of the water is the result of the hydrogen bond formed between the hydrogen of the two water molecules. The cohesive property of the water results in another phenomenon called surface tension which represents the tendency of water surface to rupture under tension.

Since both processes are the results of the hydrogen bonds formed between the water molecules of the water, therefore, option-A is the correct answer.

correct answer is a. and d.
