single quotes will suppress the special meaning of $ sign and treat it literally outputting what literally is inside of the single quotes

D supposed to be correct, but actually the question is wrongly written: `fred $USER' command would output a > prompt since it is mixing 2 quotation types. It supposed to be 'fred $USER' (single quotation type), this is easy to test and result are the same with a regular user and root.
