Express the point given in Cartesian coordinates in spherical coordinates \( (\rho, \theta, \phi) \). Note: you really only have to do the work for one, if you use a little geometry and your knowledge of the trig functions. A) \( \left(\frac{7}{4} \sqrt{6}, \frac{7}{4} \sqrt{2}, \frac{7}{2} \sqrt{2}\right)= \) B) \( \left(-\frac{7}{4} \sqrt{6}, \frac{7}{4} \sqrt{2}, \frac{7}{2} \sqrt{2}\right)= \) C) \( \left(\frac{7}{4} \sqrt{6},-\frac{7}{4} \sqrt{2},-\frac{7}{2} \sqrt{2}\right)= \) D) \( \left(-\frac{7}{4} \sqrt{6},-\frac{7}{4} \sqrt{2},-\frac{7}{2} \sqrt{2}\right)= \)
