Answer: Option (d) is the correct answer.

Explanation:

According to Bronsted-Lowry an acid is defined as the specie which is able to donate hydrogen ions when dissolved in water.

For example, $HCl \rightarrow H^{+} + Cl^{-}$

On the other hand, bases are the species which are able to donate hydroxide ions when dissolved in water.

For example, $NaOH \rightarrow Na^{+} + OH^{-}$

Thus, we can conclude that a definition of an acid is that it donates H ions when dissolved in water.
