Explanation / Answer

net cell reaction for the voltaic cell: Cr(s) l Cr+3(aq) ll Cl-(aq) lCl2(g) At anode :                     Cr ---> Cr 3+ + 3e-                       ----------(1) At cathode :    2 Cl - +2e - ---->Cl2                                    -------(2) Over all reaction is   2 * Eq ( 1 ) + 3 * Eq (2)      2Cr + 6Cl - + 6e- ---> 2Cr 3+ + 6e-    +3Cl2   ===> 2Cr + 6Cl -  --->2Cr 3+ + 3Cl2   So, option (c) is correct
