True because there is no such thing it's just what people describe someone as..like a jock or goth
Ok, it can't be C because you never place a comma in front of the adjective which is describing the noun, unless their is 3+ descriptive words.
Commas never are used when there is an <u><em>'and' </em></u>set in front of it. Commas generally mean <u><em>'and'</em></u><em /><em />. So therefore don't need to be used again, so we can eliminate B.
Not D, because it Does not contain a comma.
A is the only correct option.
