According to the Brønsted-Lowry theory, an acid is a substance that donates a proton (H+) and a base is a substance that accepts a proton. In this reaction, H₂O is donating a proton (acting as an acid) to NH₃ which is accepting the proton (acting as a base). Therefore, option B is the correct answer.None of the other options follow this pattern of proton donation and acceptance.
