Solution

The correct option is B $C_{6} H_{5} O^{-} N a^{+} + C_{6} H_{5} C H_{2} C l$
Williamson's ether synthesis:
It is used for the preparation of symmetrical as well as unsymmetrical ethers.
Alkoxides/Phenoxide consist of the conjugate base of an alcohol/Phenol and are comprised of an R/Ar group bonded to an oxygen atom. They are often written as $R O^{-} / A r O^{-}$ , where R(alkyl or aryl) is the organic substituent.
Thus Methyl phenylether can be obtained by reacting benzylchloride and phenoxide ion.
