Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

B is the correct answer. You can calculate by adding all the E° value Zn|Zn2+=0.76 Cu2+|Cu=0.34 Similarly for 2nd cell Fe|Fe2+=0.41 Cu2+|Cu=0.34 As all are connected in series So it will add up. Net EMF= 0.76+0.34+0.41+0.34=1.85V
Kindly accept my answer!
thanks sir
