Plz solve???

line is normal to second circle so passes through its centre (-1,2)

so -a + 2b +c =0..........................(1)

touches first circle so length of tangnt from center(1,0) = radius(2)

| (a +c)/(a² + b² ) | =  2

eliminate c from both equation and find an equation in a & b and check from options

by solving we get 2ab = 0

so either a or b is zero so none is correct
