Recall the Brønsted–Lowry acid-base theory, which defines acids and bases based on proton transfer.
According to this theory, an acid is a species that donates a proton (H\+ ion) to another species during a chemical reaction.
Conversely, a Brønsted–Lowry base is a species that accepts a proton (H\+ ion) from another species.
This definition focuses on the transfer of H\+ ions rather than electron pairs or hydroxide ion concentration.
Therefore, the correct description of a Brønsted–Lowry acid is: a species that donates a proton (H\+) to another species.
