If the locus of the circumcentre of a variable triangle having sides y–axis, y = 2 and lx + my = 1, where (l,m) lies on the parabola y2 = 4ax is a curve C, then
Coordinates of the vertex of this curve C is
- \(\left(2 a, \frac{3}{2}\right)\)
- \(\left(-2 a,-\frac{3}{2}\right)\)
- \(\left(-2 a, \frac{3}{2}\right)\)

Answer
(C) (-2 a, 3 2 )
