The electrolysis of dilute hydrochloric acid solution gives:

Explanation

During the electrolysis of dilute hydrochloric acid, the process involves the splitting of water molecules and ions in the solution. At the cathode (negative electrode), hydrogen ions (H+) gain electrons to form hydrogen gas (H2). At the anode (positive electrode), hydroxide ions (OH-) lose electrons, which leads to the formation of oxygen gas (O2). Thus, the correct products are hydrogen at the cathode and oxygen at the anode (Option B). Option A is incorrect because chlorine gas is not produced at the cathode in this scenario. Option C is identical to the correct answer and should be considered redundant. Option D is incorrect as sodium does not form in the electrolysis of hydrochloric acid. Option E is also incorrect as hydrogen is not formed at the anode. Therefore, Option B is the only correct answer.
