Find the orthogonal trajectories of the family of curves \(\frac{x^2}{a^2} + \frac{y^2}{b^2+k} = 1\) where k is the parameter.

A. x2-y2-3a2 log⁡x-k = 0
B. x2+2y2–\(\frac{a^2}{2}\) log⁡x-k = 0
C. x2+y2-2a2 log⁡x-k = 0
D. 2x2-y2–\(\frac{a^2}{3}\) log⁡x-k = 0
Answer» D. 2x2-y2–\(\frac{a^2}{3}\) log⁡x-k = 0
