Option E
First option will show hydrogen bonding between oxygen of hydroxyl group and hydrogen of water molecule.
Second option will show hydrophobic interactions and hydrogen bonding between sulphur of thiol group and hydrogen of water molecule.
Third option will also show hydrophobic interaction and hydrogen bonding between nitrogen of amino group and hydrogen of water molecule.
Fourth option will show hydrophobic interaction and hydrogen bonding between hydrogen of water molecule and oxygen of hydroxyl group.
Fifth option will only show hydrophobic interaction because it has more electronegative atom to show hydrogen bonding and no charge molecule to show ionic bonding.
Please rate high.
