[B]. show low resistance with positive on anode and negative on cathode, and high resistance when reversed
[C]. show high resistance with negative on anode and positive on cathode, and low resistance when reversed
[D]. show low resistance in both directions

Could any one explain how the answer will be A

The SCR acts like a very high-resistance rectifier in both forward and reverse directions without requiring a gate signal.

The answer is B why means their will be an low resistance in the forward bias and high resistance in the reverse bias.
