The difference of molarity and molality is in the units:
Molarity is expressed in mol solute / L solution;
<span> while Molality is
expressed in mol solute / kg solvent</span>
Since no other data is given, let us assume that the
contribution of methanol on the total volume is negligible. So that,
Molality = (20.3 mol / L) (1 L / 0.858 kg)
Molality = 23.66 m
<span>The closest answer is letter C. 23.7 m</span>

The units tell you:
g/cm³ = Mass (in grams) per (divided by) Volume (in cm³);
So:
109/24 = 4.54166..... ⇒ 4.54 g/cm³.
Always look at the units.
Just like for speed, you might have m/s so this is:
Distance (in meters) per (divided by) Time (in seconds).
