Which statement about water forms is true?

• A. Water occurs in three forms; solid ice, liquid water, and water vapor.
• B. The molecular formula HO2.
• C. Groundwater is located above the earth's surface and tapped by wells.
• D. Future water supplies will become more plentiful according to the TCEQ.

Answer: (A)

Water exists in three forms—solid ice, liquid water, and water vapor. This reflects how water changes with energy: heating moves it from ice to liquid to steam, while cooling reverses those changes. The statement that describes these three forms is the accurate one. The other options miss the basic facts: water’s formula is H2O, not HO2; groundwater is below the surface and accessed by wells, not above it; and claims about future water supplies becoming more plentiful aren’t a universal truth or guaranteed by the TCEQ.
