O A. The surface defined by the equation is an elliptic cone centered at ( and whose traces in the xy-plane are ellipses. O B. The surface defined by the equation is a hyperboloid of one sheet centered at and is centered around the z-axis. In the xy-plane, the trace has length in the x-direction and length in the y-direction. O C. The surface defined by the equation is a hyperboloid of two sheets centered at and whose traces in the xy-plane are ellipses. The shortest distance between the two sheets is O D. The surface defined by the equation is an ellipsoid centered at that has length in the x-direction, in the y-direction, and in the z-direction
