Answer: Option (a) is the correct answer.
Explanation:
According to Bronsted-Lowry, species which are able to donate or give hydrogen ions are known as acids. Whereas species which accept hydrogen ions are known as bases.
For example, [tex]NH^{+}_{4} + HPO^{2-}_{4} \rightarrow NH_{3} + H_{2}PO^{-}_{4}[/tex]
Here [tex]NH^{+}_{4}[/tex] is donating hydrogen ions hence it is the Bronsted-Lowry acid.
