Hydrogen is more lower than sodium in the electropositive series so it's more likely to be formed at the cathode

During the electrolysis of concentrated sodium chloride solution using carbon electrodes, hydrogen gas is formed at the cathode. This occurs because water is reduced at the cathode to form hydrogen gas and hydroxide ions1.

So the correct answer would be B. Hydrogen.

The answer should be sodium because the question said "concentrated" ... it would have been hydrogen if the question stated that it was" dilute " NaCL
