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.

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.

Ohmmeter working on pass through the current value, so this going to zero value means this resistor shorted.

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

It is overheated when it is NEAR or Approaching Zero while it is shorted when deflection is exactly at zero.

When a resistor is shorted then the current finds the low resistance path and no current flows through the resistor, that's why ohmmeter reads zero.

When the circuit is shorted high current flow through the circuit. So the resistance value is zero.

A resister does not possible to short circuit so, if meter shows near to zero it is a slight ohmic conductor.

Its option B, because short circuit has zero resistance and open circuit has infinite resistance.

Ohmmeter measures resistance, so if it measures zero then resistance is zero, which is for a wire.
