The correct option is(B): Terpineol.
Dettol is a mixture of chloroxylenol and terpineol. Chloroxylenol has 6π electrons and terpineol has 2π electrons.
Hence B is terpineol.

A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
