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.

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