Detailed Explanation

The correct answer is option  D. 

Arrow

10    : 1

-4

When comparing the conductivity, the resistance to the flow of current in forward biasing must be much larger than in reverse biasing.

Reversed Biased

Current flows

Current does not flow

Thus, if we take the ratio of resistance between reverse biasing and forward biasing it must be low.
