Which of the following cannot act as a Bronsted-Lowry base (proton recipient) in aqueous solution?

CORRECT

cannot receive another proton because then it would become $NH_5^{2+}$ , which does not exist. All of the other answer choices are fine:

$NH_3 \Rightarrow NH_4^+$

$HCO_3^-\Rightarrow H_2CO_3$

$H_2O\Rightarrow H_3O^+$

$OH^-\Rightarrow H_2O$
