What are the three physical states of fuel or matter?

• A. Solid, Liquid, Gas
• B. Liquid, Solid, Gas
• C. Gas, Solid, Liquid
• D. Plasma, Solid, Liquid

Answer: (A)

Matter exists in three common forms under ordinary conditions: solid, with a definite shape and volume; liquid, with a definite volume but taking the shape of its container; and gas, with neither a definite shape nor volume and that will fill whatever space is available. Plasma is a higher-energy state you’ll encounter in flames and certain high-energy environments, but it isn’t one of the three basic states typically taught for everyday matter. So listing solid, liquid, and gas matches the standard trio most training uses, and that conventional order is why this option is the best. The other choices either include plasma or present the same three states in a different order, which doesn’t align with the common three-state description in this context.
