b.) hydrochloric acid combining with sodium hydroxide to form nacl and water
c.) carbon-14 decaying into nitrogen-14 and a beta particle
d.) curium-246 combining with carbon-12 to form nobelium-254 and four neutrons

air quality

poor drinking water

and heavy polution

can lead to poor health

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.
