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

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

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.

The ammeter is connected in series so if an ammeter reads zero when there is no current is passing through it that is the ckt is open or disconnected.
