Answer #1

Benzoic acid has an acidic proton which can react with strong base like NaOH to form a salt.

While diethyl ether and biphenyl don't have such an equivalent proton and hence they can't react with NaOH.

After first step of extraction in organic layer B diethyl ether and biphenyl remains.
