Answer: Option (c) is the correct answer.
Step-by-step explanation:
A state of matter in which the gas molecules have very high kinetic energy and they have almost similar size of positively charged ions and negatively charged electrons then this state is known as plasma.
For example, neon signs are plasma state as they consist of glass tubes filled with gas.
Thus, we can conclude that plasma is the state of matter which is achieved if a large amount of energy is added to a gas.
