Identify the surface defined by the following equation. x2 + y2 + 4z2 + 2x = 0 Select the correct choice below and fill in the answer boxes to complete your choice. O A. The surface defined by the equation is a hyperboloid of two sheets centered at distance between the two sheets is 11 and whose traces in the xy-plane are ellipses. The shortest in the OB. The surface defined by the equation is an ellipsoid centered at that has length in the x-direction, in the y-direction, and z-direction. C. The surface defined by the equation is an elliptic cone centered at (000and whose traces in the xy-plane are ellipses. OD. The surface defined by the equation is a hyperboloid of one sheet centered at ( 1.) 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.
