All matter can only exist in these states?

• A. Change of state: Solid, Liquid, and Vapor
• B. Solid and Liquid only
• C. Gas and Liquid
• D. Plasma, Solid, and Liquid

Answer: (A)

Matter exists in a few common forms that describe how tightly particles are packed and how they move. In everyday conditions, the three familiar states are solid, liquid, and gas (often called vapor when referring to water in the gaseous form). Matter can switch between these forms through phase changes such as melting, freezing, boiling, and condensation. The option listing solid, liquid, and vapor best fits these common states because it includes all three fundamental forms without introducing a higher-energy state. The other choices miss one state or add plasma, which is a high-energy state not typically addressed in basic matter discussions.
