(B) Williamson's synthesis is a laboratory method for the preparation of symmetrical and unsymmetrical ethers. The reaction involves the nucleophilic substitution $(S_N2)$ of an alkyl halide by an alkoxide ion. The reaction is: $C_2H_5Br + C_2H_5ONa \rightarrow C_2H_5-O-C_2H_5 + NaBr$. Thus,it is used to prepare $C_2H_5-O-C_2H_5$ (Diethyl ether).
