The straight lines x(a+2b) + y(a + 3b) = a + b for different values of a & b pass through a fixed point whose coordinates are :

A)(1,-2)

B)(2, -1)

C)(1, 2)

D)None

Only one option is correct.

It seems that the question is actually an inverted form of finding the locus of the fixed point for some condition. I am unable to make any headway.
