Let each of the equations x2 + 2xy + ay2 = 0 and ax2 + 2xy + y2 = 0 represent two straight lines passing through the origin. If they have a common line, then the other two lines are given by
- A$$x - y = 0,\,x - 3y = 0$$
- B$$x + 3y = 0,\,3x + y = 0$$
- C$$3x + y = 0,\,3x - y = 0$$
- D$$(3x - 2y) = 0,\,x + y = 0$$
