@Aman.
You should think that we are talking about zero voltage but not for zero cureent. It means all the resistors except R3 contains zero resistance. So all voltage drop is across register R3 which is the total voltage drop due to current flowing through it opposed by its resistance.

It means other than R3 all resistance are zero, because of it in series connection current is same,
If I=0 then no meaning of R3.
But according to kirchoff's circuit is false.
So.
If R1, R2, R4, R5=0 then R3=6 if I=1amp.
If I=0 then no meaning of R3.
But according to kirchoff's circuit is false.
So.
If R1, R2, R4, R5=0 then R3=6 if I=1amp.

In series circuit, value of current remain same. So according to question if value of voltage measure zero across all resistor, means the value of current is zero and it same for all resistor. So answer zero.

Simple,
v1+v2+v3+v4+v5 = V,
ir1 + ir2 + v3 +ir4 +ir5 = 6,(V=6),
As per @Satosh formula,
We get v3 = V = 6v.
v1+v2+v3+v4+v5 = V,
ir1 + ir2 + v3 +ir4 +ir5 = 6,(V=6),
As per @Satosh formula,
We get v3 = V = 6v.

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.
