(b) Na
Explanation:
During electrolysis of molten NaCl, sodium metal is obtained at cathode (by reduction of sodium ions) and chlorine gas is obtained at anode (by oxidation of chloride ions). Sodium cannot be obtained by the electrolysis of brine solution as the liberated sodium will react with water to form NaOH.
Option B is the answer.
