The line parallel to x-axis passing through the intersection of the lines ax + 2by + 3b = 0 and bx  2ay  3a = 0 where (a, b)(0, 0) is

a
above x-axis at a distance 3/2 from it.
b
above x-axis at a distance 2/3 from it.
c
below x-axis at a distance 3/2 from it.
d
below x-axis at a distance 2/3 from it.

detailed solution

Correct option is C

Eliminating x, we get2b2+2a2y+3b2+3a2=0⇒ y=−3/2 which is the required line and hence below x-axis at a distance 3/2 from it.
