Water can act as both an acid and a base, depending on what it's reacting with. This is due to its amphoteric nature.

When water acts as an acid, it donates a proton (H+) to the other substance. Therefore, we need to look for a substance that can accept a proton.

Looking at the options:

A. Ca(OH)2 - This is calcium hydroxide, a strong base. It already has hydroxide ions (OH-) and wouldn't typically accept another proton.

B. All of the options - We need to evaluate all options before we can determine this.

C. NaOH - This is sodium hydroxide, another strong base. Like calcium hydroxide, it has hydroxide ions and wouldn't typically accept another proton.

D. NH3 - This is ammonia, a weak base. It doesn't have a hydroxide ion, but it does have a lone pair of electrons on the nitrogen atom that can accept a proton.

Therefore, based on the amphoteric nature of water, water would act as an acid upon reaction with NH3 (option D).
