In what ways are plasmas similar to gases? what makes plasmas different than gases?

We are asked to compare and tell the similarities and differences of plasma and gas. Well, both plasma and gas do not have a fixed shape (unlike solid), what they do is they occupy space and through that space they can be in shape like space. But, the difference between them, gases are located in the nucleus while plasma contains both positively and negatively charged particles.

Iagree c would be the answer
