Benzonitrile and aniline (shown below) are dissolved in an ether solution. Choose the best process to separate the following two compounds using an acid-base extraction. A) Add aqueous $\mathrm{NaOH}$ and extract the aniline into the aqueous layer. B) Add aqueous ${\mathrm{NaHCO}}_3$ and extract the benzonitrile into the aqueous layer. C) Add aqueous $\mathrm{HCl}$ and extract the benzonitrile into the aqueous layer. D) Add aqueous $\mathrm{HCl}$ and extract the aniline into the aqueous layer. E) These two compounds cannot be separated using an acid-base extraction.
