Answer: Option (a) is the correct answer.
Explanation:
Plasma is defined as the state of matter which is a hot ionized gas that contains positive particles and negative electrons.
Since plasma is a hot gas therefore, its particles move rapidly and independently from one place to another.
As a result, they have very high kinetic energy.
Hence, we can conclude that the statement particles are ionized and move independently of each other, best describes the arrangement of particles in plasma.
