Explanation:
The term plasma referred to that condition when the electrons are "freed" from their host atoms for a short time. It happens due to the high temperatures.
Lightning is a plasma because when a column of electrons moves from sky to ground, the air that it passes through lights up with energy. What we see as lightning is the air. In this air, the electrons are excited and giving off light. We see it as a light.
From this brief discussion, we can say that as electrons become free and become excited and then give light, lighting is a plasma.
