When NPN base is conected to P-terminal or P-probe, the transister will operate under forward bias. In forward bias the deplition layer decreases. Then more number of electrons & holes will move from one region to the other region. Hence the resistance becomes low.

Because of forward bias it has low resistance.

As the transistor becomes forward biased, it offers low resistance.

In NPN transistor, base terminal is of p-type. So, when the probe positive terminal is kept on ptype of transitor, now it is just like a transistor in forward bias, which offers a low resistance.

Since base emitter is forward biased so answer is low resistance.

But, There is closed path. So, what difference does it make, positive/negative. So, I think open is the answer

Since base junction is forward biased collector junction reprsents a low resistnce.
