The way this question is asked, (c) would indeed be correct. As you correctly noted, ethanol has nine atoms per molecule, and a 1 M1 M solution would thus contain 9 mol9 mol of atoms per litre. For comparison: acetic acid has eight, calcium chloride three and sodium chloride two.

However, they probably meant molecules in the question and not atoms — because it really makes no chemical sense to separate ethanol molecules into their atoms (they won’t separate in a solution anyway). So with that reasoning, counting ‘particles’ (whatever they may be) we arrive at 1 mol1 mol of ethanol molecules for (c), 2 mol2 mol of ions for (a), 3 mol3 mol of ions for (b) and under two moles of ions/molecules (combining both of them) for (d) (all per litre of solution).

So if that was an exam, complain and get your points acknowledged because of a badly-worded question.
