If the deflection of the galvanometer is in the same direction at both the ends of the potential meter wire, then point out the statement which is definitely not the possible reason for the.
(A) current flows is the same direction in both cases through the galvanometer.
(B) Connecting wire in the galvanometer circuit is broken.
(C) The positive terminals of all the cells are not connected at one point.
(D) The potential difference between the ends of the wire is less than the emf of the cell which is to be measured.
