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.

If they are connected in series then the voltage across R3 is zero. If connected in parallel or series parallelly subdivided then we may conclude about the voltage across R3 is non zero value i.e. 6v.

Voltage is zero means register is shorted i.e. zero valued resistor is present there and therefore the entire value of circuit voltage appears across the resistor having some value. So the right answer will be 6v.

Ohm's law is V = IR, it says that the voltage is directly proportional to the current. Also, the resistance through the all resistors is zero except third resistor which means that, the voltage will not drop in first two resistors. So, definitely 6V from the power source will be go through the third resistor. According to the ohm's law the voltage drop will be occur in third resistor which will not follow in the fourth and fifth resistors, because they given the resistance of next two resistors as zero.

In series circuit, the current through the each resistor will be same, but not voltage which will vary depends upon the resistance. If resistance is high, voltage drop will be high. We can say the resistance in terms of load. So, the voltage across the third resistor is 6V.

Except R3 Resistance, all other resistance are zero so no current flow, so r3 also no current flow and no voltage R3=0.

@Jagmel I agree with you.

AS it is given in resistors 12456 zero voltage. So either the resistance or the current in those resistors may be zero. So answer is 6V.

A starting all 5 resisters are connected 6 volts, in series connection there are all ways same voltage in all resister. Starting are IS 6V r3 resister is always 6v.
