Why don't we draw lewis dot diagrams for nobel gases

In a ground-state atom, the first two valence electrons go into the "s" orbital, so they'll be paired and it's appropriate to put a pair of dots into a Lewis dot diagram. ... Noble gases have a complete set of valence electrons (2 for helium and 8 for the others), so this one can't be a noble gas.

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.
