Resistor connected in series. Circuit current is 0.5A BUT R1245 VOLT IS 0V. So according to ohm's law V = I*R = 6V.

Resistors connected in series, So circuit current is same, Voltage across R1 R2 R4 R5 is zero. V = IR so the current remain zero, Voltage across R3 = IR3 i.e =0*R3 Final answer V3=0 option "A"

Voltage is wast in resistor. So the measuring value is Zero.

If in the string all resistors are connected in series, than if voltage across R1, R2 is zero then why there can be a voltage on R3. If there is no voltage then there must not be any current flowing.
Please answer me if you have an appropriate one.

If current through each resistor except R3 is zero. It means that they are open circuit. They have no mean in the circuit. So when current through R1 is zero it will not flow to next resistor. Hence all the resistors will have zero current.

Like R1245 resistors are 0 ohms. Like a wire. Like 6v battery dirrect connect to R3 resistor. So answer is 6v.

Here voltage drop across r1 r2 r4 and r5 is zero. That means r1+r2+r4+r5=0. So voltage across r3 resistor=6v.

I think the Current is same in series circuit. So if all the resistors are 0 ohm then the R3 will be 0 Ohm.

Correct answer is A for series case.
It would be correct if the connection is parallel.
