If shorted it will show directly zero.

I hope option A is the correct one.

Its conductivity is directly proportional to the rise in temperature. But in this condition the element offers certain resistance. So the meter shows reading near to zero but not 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.

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.

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.

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.

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

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

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

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

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