Which of the following describes the four common states of matter?

The four common states of matter are solid, liquid, gas, and plasma. In a solid, the particles are closely packed together in a fixed arrangement, resulting in a definite shape and volume. Liquids have particles that are close together but can move past one another, allowing liquids to take the shape of their container while maintaining a definite volume. Gases have particles that are far apart and move freely, meaning they fill any container and have neither a definite shape nor volume. Plasma is a state in which gas is energized to the point that some of the electrons break free from their atoms, resulting in a collection of charged particles. This state is often found in stars, including the sun.

The other options provided either include incorrect states or misrepresent the nature of matter. For instance, alloys are mixtures of metals rather than a fundamental state of matter, and while vapor is a specific term that refers to the gaseous state of a substance that is normally a liquid or solid at room temperature, it does not represent a distinct state of matter like plasma does. The crystal structure mentioned in one of the options refers to the arrangement of atoms in a solid but does not encompass a state of matter itself. Thus, the choice that correctly identifies the four primary states
