Let, the equation of the required circle is
$${x^2} + {y^2} + 2gx + 2fy + c = 0$$ ..... (1)
Circle (I) cuts the circle $${(x - 1)^2} + {y^2} = 16$$
i.e., $${x^2} + {y^2} - 2x = 15$$ orthogonally
$$\therefore$$ $$2( - g + 0) = - 15 + c$$
or, $$ - 2g = - 15 + c$$
The circle (1) also cuts the circle $${x^2} + {y^2} = 1$$ orthogonally.
$$\therefore$$ 0 = $$-$$1 + c or, c = 1
$$\therefore$$ g = 7
Now, the circle (1) passes through the point (0, 1).
$$\therefore$$ $$2f + 1 + c = 0$$ or, $$2f + 1 + 1 = 0$$ or, f = $$-$$1
$$\therefore$$ the equation of the required circle is
$${x^2} + {y^2} + 14x - 2y + 1 = 0$$
whose centre is ($$-$$7, 1) and radius $$ = \sqrt {49 + 1 - 1} = 7$$ units
Therefore, (B) and (C) are the correct option.
Note :
The condition of the circle $${x^2} + {y^2} + 2{g_1}x + 2{f_1}y + {c_1} = 0$$ cuts orthogonally to the circle $${x^2} + {y^2} + 2{g_2}x + 2{f_2}y + {c_2} = 0$$ is $$2{g_1}{g_2} + 2{f_1}{f_2} = {c_1} + {c_2}$$
