CHS1U1B13S1U1B0CHS1U1B0OH (hexane-1,3-diol) is a polar molecule due to the presence of the alcohol group (-OH). In order for two substances to be miscible, they need to have similar polarity. Option B contains another polar molecule, CHS1U1B13S1U1B0OH (methanol), that is capable of forming hydrogen bonds with hexane-1,3-diol and therefore can mix with it. The other options do not contain molecules with similar polarity to hexane-1,3-diol, so they are not miscible.
