The points of the ellipse \(16 x^{2}+9 y^{2}=400\) at which the ordinate decreases at the same rate at which the abscissa increases is/are given by
(A) \(\left(3, \frac{16}{3}\right) \&\left(-3, \frac{-16}{3}\right)\)
(B) \(\left(3, \frac{-16}{3}\right) \&\left(-3, \frac{16}{3}\right)\)
(C) \(\left(\frac{1}{16}, \frac{1}{9}\right) \&\left(-\frac{1}{16},-\frac{1}{9}\right)\)
(D) \(\left(\frac{1}{16},-\frac{1}{9}\right) \&\left(-\frac{1}{16}, \frac{1}{9}\right)\)
