Right option is (d) Cyclohexanol

Explanation: Fatty alcohols like Cetyl alcohol (popularly known as Hexa decanol), Stearyl alcohol (also called Octadecanol), and Behenyl alcohol (also called docosanol) are found to be quite suitable. A mixture of these chemicals have also been generally used and the chemicals should be 99% pure for getting the desired properties of the monolayer.
