A Correct answer
Explanation

In 1923, J.N.Bronsted and T.M.Lowry proposed a theory known as the Bronsted-Lowry proton transfer theory. According to this concept, any hydrogen species containing (a molecule, a cation or an anion), which is capable of donating one or more protons to any other substance, is called an acid. Acids classified on the basis of this concept are termed as Bronsted acids .
