Answer:
B. Its temperature
Explanation:
The different states of matter are largely influenced by both temperature and pressure. The temperature has most control over water being a gas, liquid or solid ice. If the temperature is very high, the molecules in the water increases their kinetic energy. This movement causes the compound ([tex]H_{2} O[/tex]) to break its bond. Thus, it turns into a gas. On the contrary, if the temperature is very low, the molecules of the water moves closer to each other. This causes them to solidify and turn into ice.
