Question

The range of parameter $^{'} a^{'}$ for which the variable line $y = 2 x + a$ lies between the circles $x^{2} + y^{2} - 2 x - 2 y + 1 = 0$ and $x^{2} + y^{2} - 16 x - 2 y + 61 = 0$ without intersecting or touching either circle is $a \in (25 - 15, 0)$ $a \in (- \infty, 25 - 15,)$ $a \in (0, - 5 - 1)$ (d) $a \in (- 5 - 1, \infty)$
