Since all resisters are connected in series, such that the current flowing through R3 resister is zero (open circuit) , so therefore vr3=6v.

IF CURRENT FLOWS THROUGH R3 IS ZERO, THERE MAY NOT BE ANY VOLTAGE DROP i.e v=ixr3 => 0xr3=0.when r1, r2, r4,r5=0,and r3=6ohms , current=1amp, then v3=ixr3=> 1x6= 6ohms.

In series connected resistors, the flowing current supposed to be equal. If you are measuring across any of the resistors, and the meter reads 0v, it means answer A is right. If you are measuring with the respect to common terminal, 6v reading means that R2 resistor is broken. Explanation is not correct.

6volts given to resistor(r1(0)+r2(0)+r3+r4(0)+r5(0))= we obtain the same six volts at the end.

Yes the net voltage is on the R3.

I agree with seyran.

In series connected resistors the current flowing through it ll b same but de voltage gets divided. As the question says voltage across the resistors are zero except at r3 which clearly means the entire applied voltage s across r3.

The resistor r3 is connected at first in series. So, the resistance value of the resistor r3 is high to drop that entire 6volt which may be connected to ground. So there is zero voltage appear across next coming series resistor.

In series connection current is always same so value of current across r3 is also zero hence no voltage.

If all resistors are connected in series, the current flow through the all resistors is always same. So value of current across R3 is also zero.
