Final answer:
Water is expelled from plants, wood, or fossil fuels during the combustion phase of fire.
Step-by-step explanation:
The phase of fire during which water is expelled from plants, wood, or fossil fuels is combustion (c). Combustion is the process in which a substance reacts with oxygen, releasing heat and light. Water is produced as a byproduct of the combustion reaction, and it is expelled as vapor or steam.
