Solid
-

Liquid
-
C.
Plasma
-
D.
Gas
Correct Answer:
D. Gas
Explanation:
At a temperature of 250 degrees Celsius, water exists in a gaseous state, commonly known as steam or water vapor. This occurs because the temperature far exceeds the standard boiling point of water, which is 100 degrees Celsius at sea level. In this high-energy state, water molecules move rapidly and are spaced far apart, having completely transitioned from a liquid to a gas.
