What percentage of water on the earth is used for drinking, household needs, community needs, and crop irrigation?

The correct answer to this open question is the following.

Almost 70% of freshwater water on planet Earth is used for irrigation.

Let's have in mind that although 85% of planet Earth is water, it is salty water from the oceans. The rest is water that is considered fresh that can be used by humans. Of that percentage, 70% is used for irrigation in agriculture and the rest is for drinking purposes. That is why is so important to take care of the water because in some places is scarce.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
