MHT CET 2026 Chemistry question

Identify from following cell reactions that is spontaneous under standard state of conditions

• (A)Ca(s) + Cd^{2+}(aq) \rightarrow Ca^{2+}(aq) + Cd(s),\quad [E^0_{Ca} = -2.866\,V\ \&\ E^0_{Cd} = -0.403\,V]Correct
• (B)2Br^{-}(s) + Sn^{2+}(aq) \rightarrow Br_2(l) + Sn(s),\quad [E^0_{Br^-} = -1.08\,V\ \&\ E^0_{Sn} = 0.136\,V]
• (C)2Ag(s) + Ni^{2+}(aq) \rightarrow 2Ag^{+}(aq) + Ni(s),\quad [E^0_{Ag} = 0.799\,V\ \&\ E^0_{Ni} = -0.257\,V]
• (D)2Au(s) + Zn^{2+}(aq) \rightarrow 2Au^{+}(aq) + Zn(s),\quad [E^0_{Au} = 1.68\,V\ \&\ E^0_{Zn} = 0.763\,V]
