If tangents \( P Q \) and \( P R \) are drawn from a point on
\( \mathrm{P} \) the circle \( x^{2}+y^{2}=25 \) to the ellipse

W \( \frac{x^{2}}{16}+\frac{y^{2}}{b^{2}}=1,(b4) \), so that the fourth vertex \( S \) of parallelogram \( P Q S R \) lies on the circumcircle of triangle \( P Q R \), then the eccentricity of the ellipse is
(1) \( \sqrt{5} / 4 \)
(2) \( \sqrt{7} / 3 \)
(3) \( \sqrt{7} / 4 \)
(4) \( \sqrt{5} / 3 \)
