Which of the following is a common form of matter?

Matter exists in three primary states: solid, liquid, and gas. Each of these states has distinct characteristics that define them.

In the solid state, matter has a definite shape and volume due to tightly packed particles that vibrate in place, maintaining their structure. In a liquid state, matter has a definite volume but takes the shape of its container, as particles are close together but can move past each other. In the gas state, matter has neither a definite shape nor volume; gas particles are far apart and move freely, filling the space available to them.

Since gas, liquid, and solid are all fundamental forms of matter that can be found in everyday life and have unique properties, recognizing that each form contributes to the overall classification of matter leads to the comprehensive answer that includes all three states. Therefore, choosing the option that encompasses gas, liquid, and solid accurately reflects the diverse nature of matter.
