In npn base is p juction and when postive prop is coonected to pterminal then it become forward bias and as we know in forward bias resistance is very low.

Since base is conneted to +ve probe it has a higher potential than other terminals so it makes the transistor in forward bias mode for both terminals. Hence low resistance.

Sine emitter base jnction is forward biased si it will show low resistance.

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

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

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.

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