Which equilibrium can be described as an acid-base reaction using the Lewis acid-base definition, but not using Bronsted-Lowry definition?

• A

  ${\mathrm{NH}}_3+{\mathrm{CH}}_3\mathrm{COOH}\rightleftharpoons {\mathrm{CH}}_3{\mathrm{COO}}^{-}+{\mathrm{NH}}_4^{+}$

• B

  ${\mathrm{H}}_2\mathrm{O}+{\mathrm{CH}}_3\mathrm{COOH}\rightleftharpoons {\mathrm{H}}_3{\mathrm{O}}^{+}+{\mathrm{CH}}_3{\mathrm{COO}}^{-}$

• C

  $4{\mathrm{NH}}_3+{\left[\mathrm{Cu}{\left({\mathrm{H}}_2\mathrm{O}\right)}_4\right]}^{2+}\rightleftharpoons {\left[\mathrm{Cu}{\left({\mathrm{NH}}_3\right)}_4\right]}^{2+}+4{\mathrm{H}}_2\mathrm{O}$

• D

  $2{\mathrm{NH}}_3+{\mathrm{H}}_2{\mathrm{SO}}_4\rightleftharpoons 2{\mathrm{NH}}_4^{+}+{\mathrm{SO}}_4^{2-}$
