In \( \text{NH}_3 \) and \( \text{NF}_3 \), both have pyramidal geometry with nitrogen having a lone pair. Given that \( \mu_{\text{NH}_3} = 4.90 \times 10^{-30}\text{ C m} \) and \( \mu_{\text{NF}_3} = 0.80 \times 10^{-30}\text{ C m} \), calculate the numerical ratio \( \mu_{\text{NH}_3} / \mu_{\text{NF}_3} \) expressed to two decimal places.

1. A
   \( 3.85 \)
2. B
   \( 5.24 \)
3. C
   \( 6.13 \)
4. D
   \( 7.42 \)
