In an ellipse the distance between the foci is 8 and
\( \mathrm{P}^{16.4} \) the distance between the directrices is 25 , then the

W ratio of the length of major and minor axis is:
(1) \( \frac{5}{\sqrt{17}} \)
(2) \( \frac{3}{\sqrt{17}} \)
(3) \( \frac{4}{\sqrt{17}} \)
(4) \( \frac{6}{\sqrt{17}} \)
