An ellipse is drawn by taking a diameter of the circle `(x)^2+""y^2=""1` as its semiminor axis and a diameter of the circle `x^2+""(y""""2)^2=""4` as its semi-major axis. If the centre of the ellipse is the origin and its axes are the coordinate axes, then the equation of the ellipse is (1) `4x^2+""y^2=""4` (2) `x^2+""4y^2=""8` (3) `4x^2+""y^2=""8` (4) `x^2+""4y^2=""16`
