Resistor does not short circuited when it is individual. It reads zero ohms when it is in circuit if a short in circuit.

When high current pass through the ohmmeter its start working and it is shorted then it shows zero.

It is not an ideal resistor so r is approximately equal to zero but not exactly zero when short circuit.

In case of ohmmeter, when the shot circuit condition than current pass maximum value after than circuit burn and current value will be zero this causes indicator is goes from close to zero.

When circuit is said to be short R=0 for ideal, are is small value near to zero in practicals circuit. So that ohmmeter will show near to zero value instead of zero.

Guys I'm confused, what is the real answer on that question?

At the time short resistance is very low approximately zero. So answer is correct i.e. B Shorten.

The resistance of short circuit is zero. So the correct answer is (B).

All resistance are zero that is current is no flow through the circuit then circuit is short circuit then answer is B.

I think if analog meter directly goes to zero and MCB will break down.
