Consider the circles S1 : x2 + y2 + 2x + 8y - 23 = 0 and S2 : x2 + y2 - 4x + 10y + 19 = 0
If the polars of the centre of a circle with respect to the another circle are L1 and L2, then L1, L2 are
1

2
Perpendicular and intersect at (1, 3)
3
Perpendicular and intersect at (1, -5)
4
Parallel and separated by a distance of \(2\sqrt{10}\) units
