Choice B is correct. An equation of the form ${(x - h)}^{2} + {(y - k)}^{2} = r^{2}$ , where $h$ , $k$ , and $r$ are constants, represents a circle in the xy-plane with center $(h, k)$ and radius $r$ . Therefore, the circle represented by the given equation has center $left parenthesis negative 4 comma 19 right parenthesis$ and radius $11$ . Since the center of the circle has an x-coordinate of $negative 4$ and the radius of the circle is $11$ , the least possible x-coordinate for any point on the circle is $- 4 - 11$ , or $negative 15$ . Similarly, the greatest possible x-coordinate for any point on the circle is $- 4 + 11$ , or $7$ . Therefore, if the point $(a, b)$ lies on the circle, it must be true that $- 15 \leq a \leq 7$ . Of the given choices, only $negative 14$ satisfies this inequality.
