(D) In a $P-N$ junction diode,the forward bias resistance $(R_f)$ is typically in the range of $10 \ \Omega$ to $100 \ \Omega$.The reverse bias resistance $(R_r)$ is typically in the range of $10^5 \ \Omega$ to $10^6 \ \Omega$.Therefore,the ratio of forward bias resistance to reverse bias resistance is given by:$\frac{R_f}{R_r} \approx \frac{10^1}{10^5} = 10^{-4}$ or $1:10^4$.Thus,the ratio is $1:10^4$.

The ratio of the resistance of a $P-N$ junction diode in forward bias to its resistance in reverse bias is approximately:
