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

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.

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.

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

If all resistors (except R3 are) considered having zero ohm resistance, then this condition satisfies.

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

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

R3 is an open circuit, so all other resistor voltage is 0, r3 will show 6 voltage.
