An ellipse is drawn by taking a diameter of the circle (x - 1) + y = 1 as its semi-minor 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

- x
^{2}+ 4y^{2}= 8 - 4x
^{2}+ y^{2}= 4 - x
^{2}+ 4y^{2}= 16 - 4x
^{2}+ y^{2}= 8

**Answer**

Semi minor axis b = 2

Semi major axis a = 4

Equation of ellipse = x^{2}/a^{2} + y^{2}/b^{2} = 1

**The correct option is D.**
